Hi Everyone,

I have a question about making a coordinate change to a system of differential equations. The system of equations I'm working with are the 3d Magnetohydrodynamical equations.

MHD Equations

I've just started my work on these and expect to be at it a while. I myself know what each term is dependent on so thats not a problem.

My question is simply, are there any major considerations that I need to take into account when changing to a different coordinate system with a system of equations of this size?

I'm changing from a cartesian to a spherical coordinate system.

Thanks for any help you can give.
