Hello,

 

When attempting to run a CFD simulation in Hyperworks Virtual Wind Tunnel 2019.2, the run almost immediately fails with the following dialog message: Timer stopped because of 'JOB_UNKNOWN_STAGE'. When looking at the file directory for the run, the only file generated is the AnalysisHistory.info file, which reads:

 

# -------------- Virtual Wind Tunnel Analysis History Information ------------

I was thinking that this might be an issue of not enough computing power because it is a large model. Has anyone run into this issue before?

 

Thank you so much for your help!

    Are you trying to run AcuSolve or ultraFluidX (uFX) from VWT?  If uFX, that requires high-end GPUs to run, it doesn't run on CPUs.  Note - I'm not a user of uFX, so I won't be much help beyond that...
