DMDASetGLLCoordinates
Sets the global coordinates from -1 to 1 to the GLL points of as many GLL elements that fit the number of grid points
Synopsis
#include "petscdmda.h"
PetscErrorCode DMDASetGLLCoordinates(DM da,PetscInt n,PetscReal *nodes)
Collective on da
Input Parameters
| da | - the DMDA object
|
| n | - the number of GLL nodes
|
nodes -the GLL nodes
Notes
the parallel decomposition of grid points must correspond to the degree of the GLL. That is, the number of grid points
on each process much be divisible by the number of GLL elements needed per process. This depends on whether the DM is
periodic or not.
