[petsc-users] matrix-free snes with frozen preconditioner

Dear all

I am solving a nonlinear problem using matrix-free approach in snes and I
give a preconditioner matrix via SNESSetJacobian. My preconditioner is
based on a first order scheme which is linear and hence preconditioner
matrix will not change. How do I tell snes not to recompute it ?

Thanks
