In hypermesh how do you create these corner cells which wrap around.
The following screenshot is from the Radioss example files for ALE cases to satisfy the condition where the nonreflective boundary condition must have at least one face in contact with a fluid material. I.e. iform=6 when using multi material law51.
From the users guide, the first example is easy as you can just delete out the corner cells. But how do you achieve the second valid example?
