typedef _p_DAMG * DAMG

Functions

PetscErrorCode DAMGCreateJMatrix (DAMG damg, PetscErrorCode(*crJ)(DAMG, Mat *J))

This is the function used to create the J matrix. This must be called before calling DAMGSetKSP if you want to set J and B to be different. If this is not called, by default J and B will be equal.

PetscErrorCode DAMGSetKSP (DAMG *damg, PetscErrorCode(*crjac)(DAMG, Mat *B), PetscErrorCode(*computeJac)(DAMG, Mat J, Mat B), PetscErrorCode(*rhs)(DAMG, Vec))

Set function handles to create and set values in the matrices and compute the RHS.

PetscErrorCode DAMGSetNullSpace (DAMG *damg, PetscTruth, int, PetscErrorCode(*)(DAMG, Vec[]))
