PetscErrorCode DMPlexComputeResidualByKey(DM dm, PetscFormKey key, IS cellIS, PetscReal time, Vec locX, Vec locX_t, PetscReal t, Vec locF, void *user)

Collective

Input Parameters

• dm - The output DM

• key - The PetscFormKey indicating what should be integrated

• cellIS - The IS giving a set of cells to integrate over

• time - The time, or PETSC_MIN_REAL to include implicit terms in a time-independent problems

• locX - The local solution

• locX_t - The time derivative of the local solution, or NULL for time-independent problems

• t - The time

• user - An optional user context, passed to the pointwise functions

Output Parameter

• locF - The local residual
