Hello, I’m new to preCICE and CalculiX, so maybe this is a daft question: I’m trying to set up a flexible tube like simulation starting from the 3d Tube tutorial. I have the simulation running with “nearest-neighbor” mapping, but obviously that is not ideal. I tried rbf, but that seems to be quite…

Hi All, Thanks for the help. I may have solved the issue. It was a problem with the UNV to CCX converter. When creating the mesh with Salome, Salome will create 2d elements for all surfaces. For Calculix you need to create node groups bases on the geometry (e.g. inlet, outlet, wall, interface, etc…

Hi, what elements are you trying to create? I don´t use CGX so I am not sure what elements it supports. Does it fail for linear and quadratic elements? Regarding RBF mapping, what RBF settings did you use? Thin-plate-splines (global) or Gaussian (local)? Global RBF`s are expensive even for small m…

A few ideas: Maybe it already helps if you clarify the name of your set, is it Ninterface or interface you need as argument in the ‘send’ command? But I’m not sure about this… If you call ‘prnt se’ in CGX, you can see whether the respective set contains faces. If not, maybe try to complete the (no…
