Hi @vivien!

Basically the material point defines what domain should be meshed. If you want internal flow, then the material point should be inside the model and vice versa. SimScale Staff Dheiny has explained this very well in a post [here](https://www.simscale.com/forum/t/material-point-option-in-hex-dominant-snappyhexmesh-operation/74)!

Hope this helps!

Regards,  
Barry
