SNESReset#

Resets a SNES context to the state it was in before SNESSetUp() was called and removes any allocated Vec and Mat from its data structures

Synopsis#

#include "petscsnes.h"  
PetscErrorCode SNESReset(SNES snes)

Collective

Input Parameter#

  • snes - the nonlinear iterative solver context obtained from SNESCreate()

Notes#

Any options set on the SNES object, including those set with SNESSetFromOptions() remain.

Call this if you wish to reuse a SNES but with different size vectors

Also calls the application context destroy routine set with SNESSetComputeApplicationContext()
