Hello,
I applied symmetry boundary conditions at the three domain face, but the error appears: ValueError Unpaired periodic boundary in mesh. can’t pyfr set symmetry boundary conditions at the three domain face?
Are you using high-order meshing? What meshing software are you using?
I did’t use high-order meshing, the software is pointwise.
It’s a cube with structured grid. and symmetry boundary conditions is applied on the three faces, periodic_0-l, periodic_1-l, periodic_2-l. Can symmetric boundaries be applied only on an even number of faces?
You can have as many periodic faces as you like, however you need to have a matching r and l face. ie you need a periodic_0_l and periodic_0_r. See here in the documentation (right at the bottom): [soln-bcs-name] — Documentation
Yes, but there are three surfaces that need to be set as periodic faces, two of them are periodic_0_l and periodic_0_r, and how to set the rest one?
What you are trying to do is not possible. The periodic boundary conditions pair two faces as described in the documentation. I don’t really understand how three faces can be periodic.
Three dimentional Noh problem in this artical need to be set three periodic boundary conditions.
Thanks a lot.
Symmetry conditions are not periodic boundary conditions.

OK, could you tell me how can I set symmetry conditions in pyfr?
Try a slp-adia-wall.
Regards, Freddie.
