Hello,

I was trying to run the BNSM simulation from the ET gallery on the institute cluster KANAD at IISER Bhopal in the short queue (max nodes: 16; walltime: 24 hrs) of our queuing system, but the following error came up:

The grid structure is inconsistent.  It is impossible to continue.

After this issue, I tried performing the simulation using the same parameter file in the debug queue (max:1 node), and it worked fine. But upon trying out the TOV simulation example in the debug queue, the same error came:

[1mWARNING level 0 from host n85 process 0

I am unable to understand what the issue is. I have attached parameter files, the runscript, and the output files for both the simulations (TOV and BNSM) for reference. Thanks in advance for the help.
