I would like to create tranlastion periodicity between two parallel boundary faces.
I am using the GUI, v5.0.3.
Looking at the listing, the creation of the periodic "interior" boundary seems successful, since it states:
Code: Select all
Global number of boundary faces selected for joining: 79656 Element selection successfully done. Determination of possible face intersections: bounding-box tree layout: 3D Global number of intersections detected: 752804 Vertex-Vertex intersections: 741057 Other intersections: 11747 Joining operation is non-conforming. Global number of new vertices to create: 13254 Equivalences broken for 0 edges. Edge intersections and vertex creation done. Pre-merge for 48407 global element couples. Max size of a merge set of vertices: 6 Excessive transitivity for 0 set(s) of vertices. Edge removed for 0 faces (global). Join mesh cleaning done. Edge removed for 0 faces (global). Join mesh cleaning done. Merge vertices and mesh update done. Global number of faces after splitting: 122651 Global configuration after the joining operation: Global number of border faces to add: 0 Mesh cleaning done for degenerate faces. Global number of cleaned interior faces: 0 Global number of cleaned border faces: 0 After joining Number of cells: 358452 Number of interior faces: 1103329 Number of boundary faces: 33840 Number of vertices: 420974 Joining 1 completed (6.7 s). All joining operations successfully finished: Wall clock time: 6.7
is handled, faces having periodic matches do not appear as boundary faces, but as interior faces, and
are thus not available anymore for other periodicities".
On the other hand, opening the BOUNDARY_GROUPS.case in Paraview, the two original faces are not visible anymore after extracting blocks. They are available as "interiorjoinedFaces_j01" in the separated JOINING.case.
Is there a way to double check the correct creation of a periodic boundary condition?
Many thanks in advance.
