hello everyone,

I have attached two models.
In the first one, I have defined magnets and fixed the end of the rods with Solid Mechanics.
And I want to see the two magnets attract or repel each other but it seems Comsol doesn't do the coupling automatically! coupling of Magetic and solid mechanics. Because the rods don't deform.

In the second one, I have put body forces to the magnets equal to the force that Comsol Estimates in Magnetic module. But I need Comsol to this not by me, because in that case the direction of forces is decided by me.

Is there any way that comsol will calculate the magnetic forces and put it in solid mechanics as BC?
So the rods will deform in the first model?

Thank you.
