Velocity field started diverging. Please check the mesh quality near the reported location and try refining the mesh

[tpinol]

The main chamber of the device undergoes compression. Exhaust channels have been designed within the device allowing gas to escape.

Hence, pressure inlet (~125kPa) and pressure outlet (atmospheric pressure).

The solver unfortunately stops, indicating that the " Velocity field started diverging to a value of x m/s near the position: [(x, x, x)]. Please check the mesh quality near the reported location and try refining the mesh. If the problem occured near a boundary, please check the boundary conditions. In case of doubt, please ask for assistance via our support chat.".

The “x” values seem to differ with each simulation run/iteration.

I have tried to increase the mesh quality, latest simulation run/iteration was performed with a standard, automatic, fineness 9 mesh quality with no success.

Hello, thanks for the detailed description.

Have you already gone through the steps shown in this article?

Note that the issue is more often than not with the CAD model, and not with the mesh.

Hi Ricardo,

Thanks for your help, it does seem like some CAD features were too small.

Thanks,
