Solution dependent user defined coordinate system

Could it be possible to use user defined coordinate system which is dependent on solution of a problem?
I want to solve a problem using solver sequence.
for example,
First, I solve for magnetic field.
And I define local coordinate system which is tangential to magnetic field direction.
(local x axis tangential to magnetic field)
I apply force or displacement along the local x-axis.
To be brief, I want COMSOL to transform coordinates (of stress, strain, or whatever it is) from magnetic field
direction(local coordinate) to global coordinate.
Is it possible?

Hi
I'm not sure I fully get your question, but doesnt this mean that you want to:
1) define your equations for a "local" coordinate system based on the magnetic field directions
2) solve the problem for the magnetic field
3) solve it in the next sequence for the force expressed with the function under 1)
Probably you could solve both together
But why restart in a new global coordinates ?
Finally well I havnt tought out what those coordinate formulas would look like, but this seems feasible for me.
Good luck
