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, this context may be obtained by the calling code with
DMGetApplicationContext()
Developer Note#
The handling of ctx in the use of such functions may not be ideal since the context is not provided when the function pointer is provided with, for example, DMSwarmSetCoordinateFunction()
