Hello everyone! now i am doing a simulation about flow past a 2D circular cylinder by input the python script. The problem i facing is the simulation in the Paraview does not work. where i can set the running time for my simulation? I am just a beginner of python and Paraview.

Looks like your script comes from [modulus-sym/examples/cylinder/cylinder\_2d.py at main · NVIDIA/modulus-sym · GitHub](https://github.com/NVIDIA/modulus-sym/blob/main/examples/cylinder/cylinder_2d.py)

You may want to ask them, ParaView is just a post processing tool, not a simulation engine.
