If you want to save at specific time, create the recorder at the desire time.

Thank you for response, I try to save the date only at t=2s but the program take all step times. I changed the dT to different values but nothing changed. would you write the comment that I can use for this case? Regards, Azam Abdollahi

Check the link above, the correct way to call PVD recorder is

recorder('PVD', filename, '-precision',4,'-dT', 0.5, 'pressure')

in the loop of time stepping, such as

while dt < totaltime:
if currentTime = 2.0:
recorder('PVD', ...)

Good morning, Thank you for good point, I used your command in my program. I thought it was possible to decrease the running time but it was the similar. I would like to find the hydraulic problem and it will be fast running. In this case, do you have any suggestion with opensees-FSI? Regards, Azam Abdollahi

Check dt in PVD rcorder won't change the time step. The time step has been set in analyze command. The dt here is to save data in every dt time. If you want save less data, try larger dt here.
