2D mesh extrusion and periodicity
I am trying to extrude a 2D mesh with two periodic edges. The mesh works well in 2D. Periodicity is correclty specified and no errors are thrown out when doing the mesh check.
Once extruded everything looks fine, volumes, and boundaries are correctly associated to the right parts.
However when checking for periodicity issues in the mesh check the heck fails because several shells have no twin nodes.
The mesh check reports several messages like:
"shell 50676 has node 49901 which has no twin"
What can I do? Is there another way other than manually assigning periodicity in the mesh nodes which is simply impossible due to the huge amount of nodes in the periodic faces?
Thanks a lot
can you post some pictures that illustrate the vertices of your blocking that must have the periodic boundary condition?
