DMPlexSetSNESVariableBounds

Compute upper and lower bounds for the solution using pointsie functions from the PetscDS

Synopsis

#include "petscdmplex.h" 
#include "petscsnes.h"   
PetscErrorCode DMPlexSetSNESVariableBounds(DM dm, SNES snes)

Collective

Input Parameters

• dm - The DM object

• snes - the SNES object

Notes

This calls SNESVISetVariableBounds() after generating the bounds vectors, so it only applied to SNESVI solves.

We project the actual bounds into the current finite element space so that they become more accurate with refinement.
