Hi,

all your bodies except rotor and shaft are made of air (material 1), is that on purpose?

Is the permittivity defined in your file el_steel_M800_65A.txt?

ElmerSolver says it cannot find the permittivity, so it takes the value for vacuum. I don't know if that can make the simulation fail.
to make sure that isn't the problem, you could paste the contents of the file instead of the INCLUDE command.

Also I think you should say

Variable = A

(without "Potential") in the Magnetodynamics Solver section.
And I am not sure if ElmerSolver will recognize

Simulation Type = Steady

normally it's "Steady State".

I assume you did consult the Chapter on the Magnetodynamics2D solver in the Elmer Models manual?
For general information about the structure of the sif file, see the ElmerSolver manual.

If all that doesn't help, I am afraid I cannot help you much more as I did never use the Magnetodynamics2D solver before.
