I am currently facing an issue with running FENSAP on HPC. While I have been able to run different modules such as FENSAP, DROP3D, and ICE3D standalone, I am encountering an error in the meshing process while attempting to run a multishot simulation.

After reviewing the error message, it appears that the problem may stem from setting up the incorrect FLUENT environmental variable. Additionally, it seems that the shebang line specifies /bin/tcsh as the interpreter, whereas I am currently running bash and do not have the sudo permission to change to csh/tcsh.

I have attached the environmental variable that was used for the simulation as well as the error message for your reference. I would greatly appreciate any suggestions or assistance you can provide to resolve this issue.

Thank you in advance for your time and help.
