SNESVIGetVariableBounds#

Gets the lower and upper bounds for the solution vector. xl <= x <= xu. These are used in solving (differential) variable inequalities.

Synopsis#

#include "petscsnes.h" 
PetscErrorCode SNESVIGetVariableBounds(SNES snes, Vec *xl, Vec *xu)

Input Parameters#

  • snes - the SNES context.

  • xl - lower bound (may be NULL)

  • xu - upper bound (may be NULL)

Note#

These vectors are owned by the SNESVI and should not be destroyed by the caller
