Hello Aleksander,

Please use the below boundary condition on the edges of the outer region. 

Vector potential on the inner and outer radius of the outer region and matching boundary on the two section planes .

If the above step doesnt help in resolving the error, please try non modelling one component at a time and find out the part causing the issue.Â
