Hi, I want to test the np mapping for my problem “the dam-break hitting an elastic vertical flap”. I create a tetrahedral grid and generate a file for the surface information, they are attached here. However, my coupling interrupts after a few iterations. Therefore, I do not sure if my Solid grid is…

Hi, could you post the .nam files for the complete CalculiX mesh and the log output of the solvers? NP mapping works with tetrahedral grids so I am not sure if that is the issue or not. From an initial look the files you posted seem correct.

Hi Kyle, These are all the files related to Calculix: https://drive.google.com/open?id=1zdSmAn7t98dAaq7rsuftBynxmyBW7nnN I generated a tetrahedral grid of C3D10 elements in Salome and then I converted it to Calculix format using Unical. I think that my problem is related to the solid grid or to t…

Hi Jessica, I can’t see any problems with the mesh itself. I have never had a problem generating a surface file from Salome before. I noticed in the results flap.frd that one of the vertices at the top remains zero while the other points do not. Looks like it is accidnetally fixed, but can’t see th…

[image] KyleDavisSA: I noticed in the results flap.frd that one of the vertices at the top remains zero while the other points do not. Looks like it is accidnetally fixed, but can’t see that in the files. I could not repeat this result by using CalculiX only, which indicates that the .nam files …

I couldn’t find the reason and changed to use the other mapping techniques
