Description
This error usually indicates an invalid model option has been passed to HPC solver unnoticed during the model pre-processing. This can also happen when the TUFLOW executable wasn't downloaded completely or some files were accidentally deleted.

Suggestions
Check you have NVIDIA GPU card and updated driver. Check error written in the .hpc.tlf file. For ptx file version mismatch re-download TUFLOW executable from the website.
