Help on magnetostatic problem


I would like to model a ferrofluid droplet as it deforms in a magnetic field. I know the equations, but I was wondering how to get a shape to dynamically change in free-fem, or if this is something more appropriate in a different solver.

Also, is something like the interaction between two magnetic dipoles already done? I feel like it should be but I cant find code like that that includes dynamic anywhere.

Thank you for the help

They is a lot of way to make moving domain in freefem++
