Matrix is singular : No computed solution

Mihai

Hi, I have designed an axial flux motor with Flux. If I try to simulate it, Flux gives me the following error: ' Matrix is singular : no computed solution The solving process has probably not correctly converged'

Hi Mihia,

Can you share the log and report file ?

Thanks

Hi,

May be the error message come from the mesh of the device but when I mesh and run the model that you send us, I reached to solve it without any error message.

Best regards.

Hi again,

I have the same result as Abdessamed.

I have solved you device in Flux without any issues (with Altair Flux 2020)

Can you tell us which version of Altair Flux you are using and which linear solver (Direct or iterative) ?

Thanks

Thank you very much. I only needed to have the result of the torque

Hi,

did you do anything else besides mesh the domain ?

Hi Mihai,

No, nothing else
