I am having issues with a single phase CFD simulation with massless Lagrangian particles. I have run 3 other cases successfully that are almost identical except for the flow rate profile at the boundary. I was able to successfully able to run 8 seconds with the CFD only, and the particles are injecting correctly. However, the simulation fails at t=8.4 seconds, even after I resubmitted it a couple of times to the supercomputer. Can you please send me the workaround that you shared with the originator of this post : /forum/forums/topic/error-showing-in-fluent/

The exact error message is:

Unable to parse: [free

Error: undefined read macro
Error Object: ()

Error: > (greater-than): invalid argument [2]: wrong type [not a number]
Error Object: ]

Error: ti-set-var: undefined variable
Error Object: dpm/sort-file-append?

Thanks for linking the old thread, if you search for "garbage collection" there's another thread with some information. I don't think it's anything you've done, it's something interacting (badly) on the compute side.

Hi Rob, thanks for your response. When I search for garbage collection, I only see these results (my question and another question that does not say anything relevant about garbage collection: /forum/forums/topic/unable-to-prase-with-error-the-fluent-process-could-not-be-started/). Am I missing something?

It appears that removing the monitors from the .cas file fixed the issue, as the garbage collection article suggests: /forum/forums/topic/unable-to-prase-with-error-the-fluent-process-could-not-be-started/

Thanks for your help!
