Issues with creation of periodic boundaries
Posted: Mon Apr 15, 2019 1:11 pm
Hello,
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:
Nevertheless, after importing the preprocessor.log, I can still see the two original boundary faces in the boundary regions list. This is not consistent with the Code_Saturne documentation stating that: "Once a periodicity
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.
Best regards,
Daniele
