Hi all,

I am trying to run the system coupling tutorial (reed valve and oscillating plate) using Ansys 2021 R1 on HPC. I made a bash script based on the answer from user PHutch on this thread to run the system coupling reed valve and oscillating plate examples (pictures attached).

*) The runFSI.txt file in the bash script above only contains two command, Open() and Solve()

At first, I could run the reed valve using single core example without any problem, but when I am trying to use more than two cores, the log file shows that only two cores that is requested by the system coupling (picture attached).

For the oscillating plate example, I also using trying to run the example on the HPC using bash script above, but it did not work at all. When I checked the log file, the system coupling could not connect to the CFX participant (picture attached).

In the error log file, I found out that CFX invoke command line option -mpi (picture attached) even though I did not put -mpi additional argument in the runFSI.txt file.

Is there any suggestions on how to use more than two cores for the system coupling and how to run structural-CFX coupling oscillating plate example using HPC?

Thank you.
