      Applies To        Product(s): BENTLEY HAMMER   Version(s): 08.11.02.31   Environment:  N\A   Area:  Analysis/Computation   Subarea:  N\A   Original Author: Jesse Dringoli,, Bentley Technical Support Group           Problem How can you change the Accuracy and Maximum Trials for the transient calculation engine? Product: HAMMER Version: 08.11.02.31+ Area: Analysis/Computation, Problem ID#: 52285, GENERALINFORMATION Solution By default, the accuracy and trials for the transient engine are hard coded at Trials = 40 and Accuracy = 0.001 As of 08.11.02.31, in extreme cases, you can enter special text into the notes of the transient calculation options to be able to change this. In the "notes" field of the transient calculation options, enter the following text: USE_SS_EPS_TRIALS_AND_ACCURACY This will tell HAMMER to use the "accuracy" and "trials" fields from the steady state/eps calculation options, for the transient accuracy and trials. So, in cases where the calculation engine fails due to nonconvergence, you can use this special option, then either increase the maximum trials or accuracy value in the steady state/eps calculation options.
