Questions on 2d periodic boundary condition
To solve PDEs, I am trying to make meshes on a 2d rectangular domain by using Gmsh. For the PDEs, I impose periodic boundary condition in x-direction and Neumann condition in y-direction. Accordingly, I made a geo file using "Periodic Line" as the attached file. But the periodic condition on the file does not work, that is, when I numerically solve the PDEs, a solution does not continue from the right wall after the solution reaches the left wall.
How should I fix the geo file?
Thank you.
