Hello,
We are simulating a case of water hammer, and we have the Time History with a time step of 1s, since it is a long event. In the control parameter "Time History Time Step (ms)" we set 1000 ms, but the results are 6000% above the limit. Being that the event already happened several times without consequences. By reducing the "Time History Time Step" parameter to the order of 20 ms, the results give tensions well below the admissible ones. The question is: Is it possible that the parameter "Time History Time Step" is smaller than the time step of the "Time History"? What is the criterion to select this parameter?
Thank you very much.
