  1. Hello, sorry for the late response. In fact I solved the problem. First of all the fact, that the flux project can be solved in a static scenario, without a translation part, let me think that FLUX could have some issues with geometry identification and/or remeshing during the multistatic simulation. The failure was caused by the Geometry (*.stp). For this analysis I modified an existing step-model in hypermesh. This leads to the fact, that in the exported new *.step file there where two "parts" in the part browser in hypermesh. When I modified the stepfile again by deleting one of the "parts" (not components!!!) Flux was able to solved the project. To find this problem I was in contact with the Altair Flux support. He has no idea, why this caused such a problem. He forward the Support-Ticket to Hypermesh-Support. Maybe they have an idea. Best regards.
  2. Hello, I have a problem solving a Flux 2d magneto static project (axissymmetric). The geometry check, mesh check and physical check shows no error. If I start solving the scenario this is written in the output window: Begin of physical check ... The final derivative of points defining the spline curve of material E235C must be equal to Mu0. The final relative permeability is equal to: 0.27947406883797 Please, verify the properties of the material: E235C An electric circuit exists.

I have build up nearly the same model last week, without any complication.
  3. Hello, thank you for your fast answer. Your advise helps me a lot. But do I have to model the airgab between two parts always, although the parts are in contact in reality? Regards, Magneto
  4. Hello all, I'm have build up a 3D model which 4 parts in it. This model I can mesh and solve without any problems. Now I had split 1 part into 3 party, because of different material behavoiurs. These three parts contact at the splitting surfaces. Because I was not able to mesh this geometry, I have insert a 0,5mm air gab between the parts. Now I can mesh the geometry, but without the infinitiy box. If i complete the infinity box first, it comes to a problem at meshing the volumes: "Meshing by inserting nodes has aborted. Please check mesh on lines: 331 43 44" My question is now: What can I do to avoid the meshing problems? Do I need the 0,5mm air gab between the parts? Thanks for your support. Magneto
