Fix emmental aspect after applying vtkMaterialInterface filter due to missing distance array and other arrays being defaulted
requested to merge 31-fix-the-emmental-aspect-after-applying-the-vtkmaterialinterface-filter into main
This MR fixes the emmental aspect (part 2) after applying the vtkMaterialInterface.
This emmental aspect is due to the fact that for some servers, Hercule returns a normale vector that is null, an order array equal to -1 and no interface distance.
In this development, we check that the order array range is different from -1 and that the normale vector is different from 0.
Closes #31 (closed)
