MMG 3D not run-to-run deterministic

User Help
#1

Thank you for the 5.7.1 update, it seems to work fine. However, the resulting mesh of MMG3D seems to differ every time I run the code with the same input. Version 5.6.0 was run-to-run deterministic. Is this change expected behaviour?

Edit: It seems to be related to Scotch. Is it somehow possible to use Scotch and still have deterministic results?

I too have same issue and would like to know this, thanks. Deterministic is kind of a must for my overall optimization workflow.
