PetscPointExactSolutionFn#
A prototype of a pointwise function that computes the exact solution to a PDE. Used with, for example, PetscDSSetExactSolution()
Synopsis#
typedef PetscErrorCode PetscPointExactSolutionFn(PetscInt dim, PetscReal t, const PetscReal x[], PetscInt Nc, PetscScalar u[], void *ctx);
Calling Sequence#
- dim - the coordinate dimension 
- t - current time 
- x - coordinates of the current point 
- Nc - the number of field components 
- u - the solution field evaluated at the current point 
- ctx - a user context, set with - PetscDSSetExactSolution()or- PetscDSSetExactSolutionTimeDerivative()
