I am trying to run FSI simulation in HPC cluster but I am facing the following errors.

The system coupling lof file has following:

Awaiting connections from coupling participants...
Elapsed time: 5 min. Still awaiting connection from: MAPDL-2. If you feel the participant(s) should already have connected, check participant logs and/or abort the run.
Elapsed time: 10 min. Still awaiting connection from: MAPDL-2. If you feel the participant(s) should already have connected, check participant logs and/or abort the run.

 

The fluent .trn file has following:

How to resolve this issue?

[MangeshANSYS]

Hello

1. please check all prerequisites (required libraries) are installer per https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v232/en/installation/unix_platform_libraries.html
2. please check if there is a firewall running on the nodes which might be keeping the 2 processes from communicating
3. please also see the environment variable references in these two threads to overcome issue with systen coupling
