Fail to run system coupling for 2020 r1 and r2 on HPC cluster
I am student at NAU. I used to run system coupling (version 2019r2) without any issue on our university HPC cluster. Now the university has upgraded the system from EL6 to El8 and installed new version of Ansys (2020 r1 and r2). The issue is that I am not able to run the system coupling on the new package. It appears to be an issue with EL8, or enterprise linux 8, vs EL6 since my job runs fine on EL6, but not EL8 or maybe new version of Ansys(note that I did setup on 2019r2 and have not tried 2020 version on EL6 to see if it works fine but I checked the 2020 tutorial and figured out there is no much difference about the command lines ). I would really appreciate it if anyone knows about this issue help me to solve it.
This is the error I got:
And this is contents of my input file:
