I am working on MHD simulation
 

I am working on MHD simulation using mhdFoam. I have some results now, including B isolines & U vectors. However, I also want to plot Lorentz force vectors at each time step.

I know that Lorentz force is calculated in mhdFoam code. But supopose, if I don't want to re-run my simulation, is it possible to create a new utility for post processing, by which Lorentz force is calculated?
