[petsc-users] preconditioning

[Sanjay Kharche]

Hi

I am working through the KSP examples, but I will ask for any comments in the mean time.

I have a TS code for 2D/3D heat equation, starting from ts/ex15. How can I easily modify this code to include a parallel preconditioner. As of now, I just need to add a preconditioner which is easy to program. The coefficients in my systems matrix are constant, but RHS changes at each iteration.

cheers
Sanjay
