Solving Problem - executeAlgo_c : Execution failed.

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.
The active physical application does not take account of it.
 
End of physical check.

Someone an idea which can cause this error? I have build up nearly the same model last week, without any complication.

Hi,

 

Maybe the problem come form the material that you use. When you do check physics, you get this warning:

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

 

Can you try to change the material and try to solve again the project.  

If the problem persist, can you shar the Flux project.

Best regards.

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.
