Summary0000456: scotch error in 2.1.x and not on 2.1.0
Description

I have this scotch error during the decomposePar for version 2.1.x (but it works well for 2.1.0 !!) :

Fixed in 9d7bbdb7ed0fa06e253328ddd932567968f4db52.

It was the filtering of cells with multiple inbetween faces (which sometimes occurs in ccm+ meshes)

Thanks for reporting,
