Hi! The problem is: Referenced(linked) tables, such as XLS sheets are cannot be referenced through simple MS access database connection. Direct ODBC connection has some driver issues, which i couldn't resolve on my office PC (Win7 64bit, office 2010)... But I have found an even more suitable workaround. It is kind of tricky, but It works flawlessly. The method is the following: -Database source... -Connection: Click Edit... In Database Connection dialog: -Choose: OLEDB Source as Data Source Type -Click on the "..." button at Data Source field. In Connection properties dialog: -Click Change button at Data source In Change Data source dialog: Choose Microsoft Access Database File - Data provider: same .Net Framework Data Provider -Press OK In connection properties dialog: -Database file name: Choose the .accdb you are about the use with the REFERENCED table. -Leave other field as default -Press OK (It shows ODBC connection, but there are no driver issues) -Press OK -Now you can select the referenced table from the Table name list and do everything like it would be a static table. NOTE: You have to prepare your linked references to be refeshed automaticly as the following link shows: I hope this is going to help someone someday. Best regards,

Forum Post: RE: SCADA connect with excel
Hi Attila, That's good news. So to be clear, you are using an Access database for the SCADA signals and using an OLEDB Source connection, specified as "Microsoft Access Database File" it seems. I think you are saying that you tried the in-built Access 2007/2010/2013 connection type and it didn't work right? I'm curious since behind the scenes the Access connection (Access 2007/2010/2013) is simply an OLE DB connection, however, there are a couple of subtle differences between the generic OLEDB connection in SCADA Connect and the Access connection. One such difference is how tables are retrieved. In the meantime, if things are working using OLEDB then there's no specific reason not to continue to use it. One thing with SCADA Connect is that we provide several different choices for connecting to data sources so as to try to avoid painting users into a corner. Regards, Wayne.

Wiki Page: Best practices for working with GEOPAK drainage files exported from StormCAD
Applies To Product(s): Bentley StormCAD, Subsurface Utilities Version(s): 08.11.04.54+ (StormCAD), SELECTseries 4+ (Subsurface Utilities) Area: Output and Reporting Original Author: Jesse Dringoli, Bentley Technical Support Group Background What are some best practices and things to watch out for when exporting a StormCAD (or OpenRoads SS4+) model to GEOPAK and opening that model in GEOPAK Drainage? Before Exporting First, several improvements to the GEOPAK export feature have been added in the SELECTseries 5 release of StormCAD (and SELECTseries 4 of OpenRoads). If you have not done so already, it is strongly recommendated that you install SELECTseries 5 or (when available) higher. If you're using SELECTseries 4, these improvements are also included in the latest cumulative patch set. You can read about patches here: How do I download the water and storm sewer products? How can I find out when a new version or patch is available? Cumulative patch set frequently asked questions Also, GEOPAK Drainage tends to be more sensitive to any missing data input or other data entry issues compared to StormCAD. First, Validate the StormCAD model and ensure that the data entry is correct and that results are reasonable. Here is a list of other data entry problems to be careful of: 1) The Maximum Gutter Depth, and Manning's n (inlet) and Catalog inlet curb opening length fields for catchbasin nodes need to be set greater than zero 2) All Catchbasin nodes need to reference catalog inlets and need to have at least one attached catchment. Catchbasin nodes that act as junctions should be morphed into transitions or manholes. 3) No gutters should be leaving from an inlet in sag 4) All inlets on grade need to have a bypass gutter 5) The Tc of a catchment needs to be less than the maximum duration in the IDF curve 6) Elements that are topologically inactive will still be exported to GEOPAK. These can either be addressed in GEOPAK or deleted from the StormCAD model before export. Once the StormCAD or Openroads SS4+ design is finished, (or at an appropriate stopping point) export to GEOPAK. A GEOPAK drainage library is created and the GEOPAK drainage project is created. After Exporting After addressing these items, here are some suggestions for opening the resulting GEOPAK Drainage database (GDF) in GEOPAK Drainage. If you are having difficulty finding the option to Export to GEOPAK, see these two articles: How does StormCAD V8i integrate with InRoads, PowerCivil and GEOPAK? How do I activate a GEOPAK license inside StormCAD for MicroStation? After exporting to GEOPAK Ignore the exported library (DLB) and instead use one which you configure in advance with all the particulars worked out. Things which need to be checked/verified are: Make sure all the node library items are properly referencing the appropriate cell for display Make sure the link library items have necessary information configured. For example, the GEOPAK labeler typically depends on a description for labeling the pipe. This will not be populated in the exported DLB. Create a saved set of GEOPAK Drainage preferences and load this to the drainage project. This DPF file is reusable and is simply a shortcut to get the exported GEOPAK Drainage project operational quickly. The reason this is necessary is that the exported GEOPAK drainage project will not contain some settings which are not part of the StormCAD project. For example, GEOPAK uses slightly different junction loss calculations and the necessary constants will not be defined in the exported file. This really only matters if calculations are needed but it does generate some error message popups when opening the GEOPAK file. Open the GEOPAK Drainage project GDF file Once open load the preference file noted in 1B which also in turn loads the library noted in 1A In the GEOPAK Drainage menu: Components > Nodes > Update All Component > Links > Update All Open the GEOPAK Drainage labeler and complete your annotations as needed. If you need profiles for annotation or projection to a centerline, then these will need to be recreated inside GEOPAK Drainage.

Applies To Product(s): StormCAD Version(s): 10.00.xx.xx, 08.11.xx.xx Area: Installation Original Author: Scott Kampa, Bentley Technical Support Group How To: How does StormCAD V8i integrate with InRoads, PowerCivil and GEOPAK? Background Below are details on how StormCAD integrates with InRoads, PowerCivil, and GEOPAK: Inroads An InRoads Storm and Sanitary file can now be imported/exported inside of the standalone platform of StormCAD via file > Import/Export. When using StormCAD within Microstation, you can do this via the StormCAD menu > Project > Import > InRoads. This functionality was added in version 08.11.00.34 of StormCAD. In version 08.11.00.40, the ability to do this in the AutoCAD platform was added, along with the ability to retain/persist relevant calculated results during export and persist curved pipes (bends will be added in the StormCAD model). All subsequent versions include this functionality as well. PowerCivil You can now use StormCAD within the PowerCivil for Americas environment, using the "StormCAD for Powercivil for Americas" shortcut. You will be able to lay out and compute your StormCAD model, while using the PowerCivil tools. Also, while you are in the "StormCAD for PowerCivil for Americas" platform, you can import/export a GeoPAK drainage file via the StormCAD menu bar > Project > Import. This functionality was added in version 08.11.00.24 of StormCAD. All subsequent versions include this functionality as well. GEOPAK When using StormCAD inside of Microstation with a Geopak license, you can import/export a GEOPAK drainage file, via the StormCAD menu bar > Project > Import > GEOPAK Drainage. This functionality was added in version 08.11.00.24 of StormCAD. For issues activating the GEOPAK license in StormCAD for MicroStation, please reference the following link: http://communities.bentley.com/products/hydraulics___hydrology/w/hydraulics_and_hydrology__wiki/11344.how-do-i-activate-a-geopak-license-inside-stormcad-for-microstation.aspx All subsequent versions include this functionality as well. NOTE: With PowerGEOPAK, the integration process is not automated. You will need to manually change the configuration files in order to see the integrated products.

The GEOPAK "applications" menu does not appear when opening StormCAD for MicroStation, so the Import/export GEOPAK menu items do not appear for StormCAD. Steps to Resolve Starting with the SELECTseries 2 release of GEOPAK, the Applications menu does not appear automatically. This needs to be available because GEOPAK needs to be activated in order for the import and export GEOPAK menu items to be available from the StormCAD menu. This example below uses GEOPAK Select Series 2, so you should replace the 2 with whatever Select Series version of the software that you have. To fix this, you will need to add the -wsLoad_GEOPAK_SS2=1 switch to your StormCAD for MicroStation shortcut: 1) Navigate to the StormCAD for MicroStation shortcut 2) Right-click on the shortcut and select Properties 3) In the “Target” field, scroll all the way to the right 4) Add a space and then enter “-wsLoad_GEOPAK_SS2=1” 5) Click Apply, then OK. Then run the shortcut 6) Activate GEOPAK. Once this is complete the import/export GEOPAK menus should be available. After everything is activated the menus should look like this: This is the import menu This is the export menu See Also How does StormCAD integrate with InRoads, PowerCivil and GEOPAK?

Forum Post: RE: SewerGEMS+ Extreme load factor+DIversion
Hamid, Since pipes are initially dry, it can take some time to reach a steady condition at the beginning of the simulation. You may want to extend the duration of the first set of inflows for a bit longer to compensate for this. I'm not certain what you mean by setting the "calculation time" to one minute.

Wiki Page: Modeling a flow split (diversion) with the SewerCAD or StormCAD numerical solver
Applies To Product(s): Bentley SewerGEMS, Bentley SewerCAD, Bentley StormCAD Version(s): 08.11.XX.XX Area: Layout and Data Input Original Author: Terry Foster, Bentley Technical Support Group Background I would like to model a split flow in Bentey SewerCAD, Bentey StormCAD, Bentley SewerGEMS, or Bentley CivilStorm. If you are using Bentley SewerGEMS or Bentley CivilStorm the steps below to enter a diversion rating table only apply to certain numerical solver. In SewerGEMS the directions will apply to the GVF rational solver (StormCAD) and the GVF Convex solver (SewerCAD). The directions will apply for the CivilStorm GVF rational solver (StormCAD). **Please note that SewerGEMS and CivilStorm also come with the implicit and the SWMM solvers, which are both fully dynamic solvers, that do not require you to enter a flow split as it's taken care of automatically. You can find more information as to which solver is best to use for your model in this wiki ** Steps to Accomplish First, you will need to identify one of the conduits coming out a manhole or catch basin as a diversion link. If you double-click the conduit to view the properties you will find a property field titled "Is Diversion Link?". Set this to "True" and new property fields will be available to enable the addition of a diversion rating curve. To set of the diversion rating curve, click the ellipsis (...) button in the field "Diversion rating curve". This will open a new dialog where you can enter a table for incoming flow versus diverted flow. In other words, for a given upstream incoming flow you are defining how much of that incoming flow will travel down the pipe marked as the diversion. The remaining flow will go down the other downstream pipe. What you are doing here is manually defining how the flow split functions. For example, you could assume a 50/50 split. You can also have no diverted flow for a part of the curve and only allow diverted flow once it reaches a certain flow amount. In the above example, when you have an incoming flow of 10 cfs none of it will be going down the diversion pipe; all of the 10cfs will be going down the other pipe. This might happen if the diversion pipe has a higher invert and the water surface has not reached that elevation yet. Once you have this set up you can then compute the model. The flow should split based on the diversion rating curve that you entered. Using The Implicit or Explicit solver in SewerGEMS or CivilStorm to develop the diversion rating table Sometimes you may not always know what this diversion rating curve is. If you have access to Bentley SewerGEMS or Bentley CivilStorm, you could use these to help. SewerGEMS and CivilStorm use the Dynamic Wave solver (Implicit solver or SWMM solver) and can model split flows in a storm or sanitary system automatically. As a result, you can use these programs to help create the diversion rating curve, which you can then use in StormCAD or SewerCAD. To check which solver you have selected go to View > Calculation Options and double click the active calculation option with the red check mark on it. Check to see what the active numerical solver is set to. To do this, set up a small model with the manhole in question and incoming/outgoing pipes, with a load on the upstream node covering a range of expected flows. Compute the model and look at the flow through one of the conduits, then build your diversion rating SewerCAD or StormCAD based on these results. Using CivilStorm as an example, below is a simplified model: At manhole "X", an Inflow (Wet) Collection has been set up to represent flow into the system. You can see the steps by the graph for the different times and flows. When the flow goes through Manhole "Y" it is split between Pipe "B" and pipe "C". How much flow goes into each pipe will depend on the diameter of the pipe and the invert elevations. As noted above CivilStorm and SewerGEMS implicit and explicit solvers can calculate the split flow automatically. After computing, the results are graphed below. You will see the flow for pipes A, B, and C. You can enter the data from points on the graph into the diversion rating curve in StormCAD or SewerCAD, or you can copy/paste from the data tab. If you are going to copy/paste, you would copy the data from the column of the upstream pipe to Upstream Flow (cfs). You will copy the data from the pipe that will be the diversion pipe to Diverted Flow (cfs). For a given "step" of the flow in the upstream pipe, that flow amount would be the "Upstream flow" on the diversion rating curve for StormCAD or SewerCAD. At the same time you observe that upstream flow, you would look at the flow in one of the downstream pipes and use that as the "diverted flow" on the diversion rating table. The pipe you pick is the one that you will be using as the diversion link in StormCAD or SewerCAD (or with the GVF-Convex or GVF-Rational solver). For example when using the implicit or explicit solver in SewerGEMS or CivilStorm, if you have a flow of 10 L/s in the upstream pipe in the first "step" of the pattern, and if you select pipe "C" as the diversion link, if pipe C has a flow of 3 L/s at the time you observe the 10/Ls in the upstream pipe, then 3 L/s would be used in the diversion rating table as the "diverted flow". NOTE: you may need to extend the duration of the first set of inflows since the initially dry pipes will take time to fill In summary, if you have a model with several complicated diversions you may want to consider using CivilStorm (Implicit solver) or SewerGEMS (Implicit solver), as they are best suited for more complicated flow split situations. See Also Modeling a flow split (diversion) in SewerGEMS or CivilStorm Is it possible to model a weir within a catch basin or manhole in the the storm-sewer Haestad products?

Forum Post: RE: SewerGEMS+ Extreme load factor+DIversion
Per the article, you use the results for the two downstream pipe for the range of flow to develop the rating curve. The total incoming flow from the upstream pipes, that would be the "Upstream flow" in the diversion rating table, and the flow you see in the downstream pipe that you will use as the diversion pipe would be the "diverted flow". I've amended the article to add some clarification.

Wiki Page: Transient Force Calculations in HAMMER
Applies To Product(s): HAMMER Version(s): 08.11.xx.xx Area: Output and Reporting Original Author: Scott Kampa, Bentley Technical Support Group Transient Force - Background This article provides background information on transient force in Bentley HAMMER Note : for background information on Transient Force calculations, see the section further below. By default, HAMMER does not calculate force results, but you can set up the model to run these calculations. To do this, go to Analysis > Calculation Options and double-click the active Transient Calculation Option to view the properties. In the properties, find the attribute "Calculation Transient Force?" and set this to True. Once this is done, compute the model. There a couple of different ways to view the results. First, under the Time Histories tab of the Transient Results Viewer, you can choose "Force X", "Force Y", "Force Z" "Force Magnitude", or "Force X, Y, Z and Magnitude" as the "Graph type". Select the end point where you would like to see the force results, then click "Plot". *For more information on how the forces are calculated please see this wiki technote . In addition, you can see the magnitude of the force, as well as the force in the x, y, and z directions at each node in the model by viewing the Transient Output Log (Report > Transient Analysis Reports > Transient Analysis Output Log). Search for the section "Maximum Forces at Every Node" for the data. This will list the maximum force for each node and the time that the maximum force occurred. Transient Force Calculations To understand the meaning of the X/Y/Z force values (fx, fy, fz), think of the model plan view, or the top-down view. Think of the node in question as the 0,0 origin of a standard graph, with the X axis extending to the right and the Y axis extending up. The "X" force would be the force exerted from left to right. So, a negative value would mean a force exerted towards the left of the node. The "Y" force would be the force from down to up. So, a negative value for Y would mean a force exerted down. The Z force would be the force in the Z direction - perpendicular to the plane of the graph. So, a negative Z force would mean a force exerted toward the ground. These X/Y/Z values are useful when determining required bracings (thrust blocks, restraints, etc) since it gives you the force for the important 3 directions, when the total (resultant) was at it's maximum. Note: - There are two components of force at a pipe end section (pipe end point at a node): Longitudinal force and Transverse force. These two forces affect the total component forces in X, Y and Z direction. - Longitudinal force at a pipe end section is affected by the pipe cross-section area, velocity, and pressure. - Transverse force is affected by the direction of the pipe and the weight of the fluid in the pipe. - Pipe direction is affected by the pipe start and stop node coordinates (X, Y, and the elevation Z). For this reason, force calculations will work best with a scaled model. If the model is not scaled, you should be mindful of the coordinates, as a shift in the coordinates can impact the force calculations. For instance, if you manually lay out a system that is meant to have no gradient in the Y direction (i.e., a horizontal line), if there the line is not exactly horizontal, it will make the results different compared to a horizontal layout. - The weight of fluid is affected by the pipe length and pipe cross-section area. - Pipe length can be the user-defined length or scaled length. You will want to make sure the data is accurate, as length can be important in force calculations. For a vertical pipe, the start and stop node can have the same X-Y coordinates (or close to overlapping). The user only needs to get correct pipe length and node elevations to see accurate results, though the plan view appearance of the model may not be ideal. Note: HAMMER models can be exported to an i-model (File > Export > Publish i-model). This file can then be opened in MicroStation to see a 3-D representation of the system, along with results that are available in the Properties dialog. Starting with HAMMER V8i SELECTseries 5, the user can also export to a Map Mobile i-model to view the system on handheld devices or tablets. - In determining the pipe direction, only pipe start and stop node coordinates (X, Y and elevation Z) are used. The bending points in the drawing of a pipe are ignored. You will need to place junctions (or another node element) at the vertex. Additional explanation of force calculations in HAMMER is found in the Help documentation under Contents > Modeling Capabilities > Hydraulic Transient Pressure Analysis > Analysis of Transient Forces and also under Contents > Bentley HAMMER V8i Theory and Practice > Transient Forces. See Also The z force for my model appears unusually large. Why? Are pipe bends (vertexes) used in the force calculations?

Forum Post: RE: SewerGEMS+ Extreme load factor+DIversion
From the graph you just provided, it looks like the inflows are fixed. To develop the rating table you'll need to run a range of inflows. You could either run multiple simulations with different inflows and observe the downstream flows, or use the method described in the article whereby a hydrograph is used as the inflow, where the flow varies in steps over time.
