[Nek5000-users] Nekmerge question

Hi Jean-Christophe,


It should inherit the bcs from the originating meshes

and it will replace any bcs on shared interfaces with E-E
automatically.

Very important that the meshes you are merging are compatible
with conforming interfaces and no domain overlap --- the
merge code does not check for these conditions.
