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

Input Parameters#

  • da - the DMDA object

  • n - the number of GLL nodes

  • nodes - the GLL nodes

Note#

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 DMDA is periodic or not.
