Hi! I am new to HPC, and I am trying to run a multiphase simulation in ansys fluent 2021 r2. I get the following error: 

Error at host: Unable to open C:/Users/Desktop/HPC_Sim/fluent-1.cas.h5 for writing.

===============Message from the Cortex Process================================

Compute processes interrupted. Processing can be resumed.

Error: Unable to open C:/Users/Desktop/HPC_Sim/fluent-1.cas.h5 for writing.
Error Object: #f

Warning: An error or interrupt occurred while reading the journal file.
Some commands may not have been completed.

Halting due to end of file on input.

Here is the script and slurm file I used. Can someone help me figure out the error?
