How to have a specific sampling rate for results in a transient analysis with auto time stepping on?
Dear Ansys Forum Users,
I wish to have a sampling rate of 2000 Hz for the results of a transient analysis in Ansys Mechanical. I have tried to use a fixed time step of 5e-4 s; however, the model fails to solve due to this time step being too large. I have therefore activated automatic time stepping with an initial time step of 5e-4 s, a maximum time step of 5e-4 s and a minimum time step of 1e-12 s. The model solves using automatic time stepping.
I have used the following commands to specify output of nodal solution results at a sampling rate of 2000 Hz for a 5 s simulation:
Unfortunately, the results I get are not at an exact sampling rate of 2000 Hz. The time step between each result isn't always 5e-4 s, which is what I require. Does anyone know what settings I need to specify to ensure the results output I have requested is given at specified sampling rate?
Thank you for any help.
