I am designing a lens using quasi-periodic structures using CST Studio. When I change some parameters like diameters, periodicity, etc, the simulation does not work (just for certain values). I start the simulation it reaches 37%, the state of the simulation is: "Creating Tetrahedral Mesh: Surface meshing". And it can be like that for hours and there is no improvement.
I think the meshing does not converge. How could I solve it to see my results without these problems? The structure is relatively simple and it should not take that much to be simulated.
Hi Pepe. I am an economist with some knowledge about statistical simulations. Since you mention your goal is to design an object (a lens), I understand the context of your problem, but I do not know about CST Studio and quasi-periodic structures. Therefore, my suggestion comes from analogies: there must be some restriction(s) your object must have for us to call it "a lens", so you must include them into the definition of the problem (simulation). In other (your?) words, you must make CST Studio's quasi-periodic structures work within specific boundaries.
It seems that your mesh is very big. Reduce the mesh and try it please.
