I want to do the following:

Through Rocky PrePost, start a simulation for 20 seconds.
total_time = 20, but pause the simulation every 4 seconds and perform a certain operation.
stop_time = 4

# Describing the study
study = project.GetStudy()
study.SetName('My Simulation')
study.SetDescription('My DEM Simulation')
study.SetCustomerName('My Customer')
study.DeleteResults()

# Solver.
solver = study.GetSimulatorRun()
solver.SetSimulationDuration(total_time, 's')
solver.SetTimeInterval(0.25, 's')
solver.SetUseCompressedFiles(True)
solver.SetSimulationTarget('CPU')
solver.SetNumberOfProcessors(20)

study.StartSimulation(skip_summary=False, delete_results=True)

While True:
    current_time_step = GetTimeStep('current').GetTime()
    if current_time_step % stop_time == 0:
        StopSimulation()
        print("stop.")
        break
        study.StartSimulation(skip_summary=False, delete_results=False)

I understand that there are many errors here, but the main idea is as follows: there is a simulation - a total of 20 seconds. Every 4 seconds, it needs to be paused, perform 'block 1', and then resume the simulation. Can you advise how to implement this?

It'll be an API operation, so check that part of the documentation (in with the Ansys DOC as of 2024R1). Not sure why you want to delete the data every 4 seconds?

Not certainly in that way

I want to run the calculation for 20 seconds

but stop the calculation every 4 seconds
(upload some data)
continue calculation

and so on

I actually can't solve the problem

how to put  in "t_1" variable
current calculation time value

and check if necessary (multiples of 4) then stop the calculation, perform the action, continue the calculation

if you can tell me how to implement something like this, or where there might be an example
I will be very grateful
I looked at the Rocky prepost manual until I found answers to my questions in it.

thank you in advance for your help

I can't cover APIs on the public forum as they're generally very specific. I'll check for examples, but suspect there won't be much we can do.

And having heard back. It's not available via the API at present, but pyRocky may work if you use threads. Check the Ansys GitHub for examples/ideas - we can't offer much assistance here.
