PetscBdPointFn

A prototype of a pointwise boundary function that can be passed to, for example, PetscDSSetBdResidual()

Synopsis

typedef void PetscBdPointFn(PetscInt dim, PetscInt Nf, PetscInt NfAux, const PetscInt uOff[], const PetscInt uOff_x[], const PetscScalar u[], const PetscScalar u_t[], const PetscScalar u_x[], const PetscInt aOff[], const PetscInt aOff_x[], const PetscScalar a[], const PetscScalar a_t[], const PetscScalar a_x[], PetscReal t, const PetscReal x[], const PetscReal n[], PetscInt numConstants, const PetscScalar constants[], PetscScalar f[]);

Calling Sequence

• NfAux - the number of auxiliary fields

• uOff - the offset into u[] and u_t[] for each field

• uOff_x - the offset into u_x[] for each field

• u - each field evaluated at the current point

• u_t - the time derivative of each field evaluated at the current point

• u_x - the gradient of each field evaluated at the current point

• aOff - the offset into a[] and a_t[] for each auxiliary field

• aOff_x - the offset into a_x[] for each auxiliary field

• a - each auxiliary field evaluated at the current point

• a_t - the time derivative of each auxiliary field evaluated at the current point
