Hello all,

I am running FSI studies with System Coupling and Fluent, and am having trouble opening a rst file that did not converge. I am trying to open the file using command line execution on my school's interactive node on their HPC cluster. The last message I receive is a Signal 15 error.

Here is a screenshot of a normal case.

It looks like more than 1 program is accessing the RST file. Try closing/exiting other programs.

Apologies. I'm not quite sure how to do this in an interactive HPC node. It's a linux based CUDA node through which I have to open the Ensight using the command line. I only ever use Ensight on this server, so nothing else should be running.
I'll do some research as to how to see other programs that are running. Thank you.

Hello again, I'm back here with non-converged cases. It seems it's not actually the non-converged case it can't open, but the file itself I believe has a corrupted header. When I try to open the individual rst files from the distributed solve most of them won't open in Ensight for certain reasons.
It'll either say "improper or incomplete file format, file contains an unrecognized format, trouble opening filenames, solution header ierr=12"
or "file12.rst doesn't exist or can't be opened, file access failure, premature EOF, ierr=6"
How can I open these files to inspect them? The individual rst files are over 3GB each. I wish I could open them with notepad and just check the header.

Internet search for "text editor large files" gives several programs that are capable.
Does this happen with most any or all Ensight runs on this HPC?
Some institutions have file / folder quotas? It is possible you are hitting this?
Do you have any other hardware to try same run on?
Perhaps try a non-Distributed solver run.
