[Getdp] Magnetic force

Dear Christophe,

I am trying to calculate the force on a paramagnetic body by f = chi/mu_0 
(B * nabla) B. Is it possible to evaluate something like Grad[CompX[{d 
a}]] in the post processing of a magnetostatic problem? My first straight 
forward attempts to do so failed. Is there a hack to get it? If not: is 
there an alternative approach to calculate the force (-density)?

Best Regards

Matthias
