I 4got to add that sometimes u get better structured meshes (certianly in gmesh) if u partition the piece into 3 and 4 sided sections - slice them in ur CAD program and re-join them b4 exporting.
then try these gmesh comands
then i get something …
within MW u can use customised comands for gmsh - paste the following into the "custom Gmesh commands" in meshing parameters and u will get a reasonable 2d mesh
Mesh.Algorithm = 11;
Mesh.ElementOrder = 2;
Mesh.RecombinationAlgorithm = 3;
Mesh.Reco…
thank you disla for looking at this - i had a little play with this and managed to get more sense out of it by swapping the contact surfaces as u suggested. I'm afraid some of the other suggestions u made were beyond my level of understanding. "Proj…
