Coupling magnetic and mechanical models

[ftrillaudp]

Dear all,

I am trying to compute from magnetic forces the mechanical deformation on a coil as well as the stresses. Here is my case studies following the post: viewtopic.php?f=3&t=6954, on magnetic computation on a coil with an iron core.

The solver does not complain but it s seems that the forces are not computed correctly since the magnitude of the strain and stress is way too small.

I have attached the full case study.

Best,

Frederic

Body 1
Name = "SOL001"
Target Bodies(1) = 1
Equation = 2 3
Material = 1
Body Force = 1 2
End

I tried this change but still had the same warning
Body 1
Name = "SOL001"
Target Bodies(1) = 1
Equation(2) = 2 3
Material = 1
Body Force(2) = 1 2
End

Body 2
Name = "SOL002"
Target Bodies(1) = 2
Equation(3) = 1 2 3
Material = 3

Then I did this and had results

Hi

Each "Body" and can only be associated to one "Equation" and "Body Force". Unfortunately the naming is not too helpful. Equation should be understood as "all solvers associated with this body" and body force is "all r.h.s terms associated with this body".

Dear Kevin and Peter,

Thanks for the time. With the modified case.sif, I get the expected displacement field. All good.

Best,

Frederic
