#include "petscpc.h" PetscErrorCode PCBDDCSetDivergenceMat(PC pc, Mat divudotp, PetscBool trans, IS vl2l)Collective on PC
| pc | - the preconditioning context | |
| divudotp | - the matrix (must be of type MATIS) | |
| trans | - if trans if false (resp. true), then pressures are in the test (trial) space and velocities are in the trial (test) space. | |
| vl2l | - optional IS describing the local (wrt the local mat in divudotp) to local (wrt the local mat in pc->pmat) map for the velocities |
Notes: This auxiliary matrix is used to compute quadrature weights representing the net-flux across subdomain boundaries
