PCSetCoordinates

sets the coordinates of all the nodes on the local process

Synopsis

#include "petscksp.h" 
PetscErrorCode PCSetCoordinates(PC pc, PetscInt dim, PetscInt nloc, PetscReal coords[])

Collective on PC

Input Parameters

	pc	- the solver context
	dim	- the dimension of the coordinates 1, 2, or 3
	nloc	- the blocked size of the coordinates array
	coords	- the coordinates array

Notes

coords is an array of the dim coordinates for the nodes on the local processor, of size dim*nloc. If there are 108 equation on a processor for a displacement finite element discretization of elasticity (so that there are nloc = 36 = 108/3 nodes) then the array must have 108 double precision values (ie, 3 * 36). These x y z coordinates should be ordered for nodes 0 to N-1 like so: [ 0.x, 0.y, 0.z, 1.x, ... , N-1.z ].
