Hi,

Every time I try to mesh a geometry with a high number of cells (usually above 90-100M) I get an "Invalid Integer Cast" error at the very end of the meshing (when it says "optimizing mesh").
I have tried to mesh on different processors, on a different number of processors, different simulations, different mesh sizes, without any luck...
See the picture attached for what Starccm+ returns (I only did screenshot, could not copy paste here).
Any idea?

thanks for your help!

The problem looks like it is in the partitioner.

This is likely a bug, so I would give the case to your support engineer.

However, have you tried:
1. meshing in serial
2. Clearing any existing grid before meshing this one
