PetscSimplePointFn#

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

Synopsis#

PETSC_EXTERN_TYPEDEF typedef PetscErrorCode(PetscSimplePointFn)(PetscInt dim, PetscReal time, const PetscReal x[], PetscInt r, PetscScalar u[], void *ctx);

Calling Sequence#

dim - The coordinate dimension of the original mesh (usually a surface)
time - The current time, or 0.
x - The location of the current normal, in the coordinate space of the original mesh
r - The layer number of this point
u - The user provides the computed normal on output
ctx - An optional user context

Note#

The deprecated PetscSimplePointFunc works as a replacement for PetscSimplePointFn *
