ERROR: error occurred executing acuPrep / ERROR :No RUN command found / Hypermesh CFD 2025

Hi,

I have spent the past two consecutive days attempting to run a CFD simulation using HyperMesh. However, every time I attempt to run the simulation, it gets canceled and the following log file appears ( attached image).

I have successfully run other simulations earlier this week without encountering any such issues. I don’t believe the issue is in the pre-processing stage, as I carefully repeated the setup multiple times to make sure nothing was missed. However, I am still learning and don’t have much experience, so I might be making some simple mistakes.

If anyone can help me, I’d really appreciate it!
