Subject: solve PDEs in spherical coordinates

Hello,

I would like to solve/integrate a system of 4 PDEs over /inside a
spherical domain.?? How can I accomplish this in PETSc??? Do I need
convert the equations into Matrix-vector form first (along with all the
messy metrics)? Or can PETSc do this for me??? My goal is to be integrate
this system of PDEs for a spherical domain of arbitrary radius.

Thanks,
Mark
