Hi Tuomas, This is easy with quads, as we just extrude a periodic interval. For triangles I suggest to mesh a cylinder embedded in 3D, and then prune it, like we do for the other periodic meshes.

all the best --cjc

Hi all,

Is there an easy way to create a rectangular mesh with two periodic boundaries? PeriodicRectangleMesh is a torus so all 4 sides are connected. I'd need a triangular RectangleMesh where only sides x=0 and x=Lx are connected.
