Hi, I'm pretty much a newbie at Mathematica and am struggling getting going TBH.

I want to solve the Landau Lifshitz Gilbert equation - to produce an animation of damped precession.

The first part - undamped precession - of the equation is pretty simple - dM/dt = MxH with the result being steady precession of the vector M about the vector H. so I thought, walk before I can run and try that.

Any pointers or examples that might get me started on solving this? I've been looking at NDSolve and tried throwing a vector into that, have looked for other examples. Do I really need to work in cartesians for this to work?

Thanks!

Dave
