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.
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.
