Good day, thanks again for the prompt reply. I have followed the procedure as suggested, nevertheless I still have the issue of not been able to keep the mesh symmetry (4 triangles diagonally crossed in a center node) once the simulation is running. For example, the first picture is the original mes...

Thank u very much for the prompt reply. By "loosing their arrangement" I meant that the triangles where not kept in this diagonal form and took a random configuration. As if I was not splitting the quads into tri at all. You are right, I am editing the mesh in such a way. I will take the c...

Good day all, I am able to split my quads into 4 crossing triangles using the option: utilities/preferences/Meshing->Symmetrical Structures. And it works perfectly. The issue is, that when I run my anal sys (using PFEM) even at time 0.0 (no deformations or whatsoever) the triangles immediately loose...

Dear all, good day: I would like to mesh my geometry with 4 diagonally intersecting triangles inside a quad. This I want to do it for the sake of reducing volumetric locking. 4t.png I Have looked in GiD for some time now, and I have not been able to find a suitable function to perform that. Is there...
