Hallo, I have built a 3D Modell of a electrically excited synchronous machine. During the solving a problem happend ' Conductive region : SIGMA must be <> 0Impossible to continue to solve problemIncoherence of physical properties'. It can not be solved. But I dont know why it happens.

Hi,
You are right when I solve the project I get the error message : ' Conductive region : SIGMA must be <> 0Impossible to continue to solve problemIncoherence of physical properties'.
To fully understand the problem, I proceed as follows:
I delete all the isotropic resistivity of the materials
I solve the project >> the solving is ok
I add the resistivity of the first material: ALLOY_409
I solve again the project >> the solving work well
I do the same thing for the materials: GENERISCHER_MAGNET and VACODYM_677_AP
The solving work well
You will find attached the Flux project ready to solve.
I will check in more details, why with initial project we get the error message.
Best regards.
