SNESView#

Prints or visualizes the SNES data structure.

Synopsis#

#include "petscsnes.h"  
PetscErrorCode SNESView(SNES snes, PetscViewer viewer)

Collective

Input Parameters#

snes - the SNES context
viewer - the PetscViewer

Options Database Key#

-snes_view - Calls SNESView() at end of SNESSolve()

Notes#

The available visualization contexts include

PETSC_VIEWER_STDOUT_SELF - standard output (default)
PETSC_VIEWER_STDOUT_WORLD - synchronized standard output where only the first processor opens the file. All other processors send their data to the first processor to print.

The available formats include

PETSC_VIEWER_DEFAULT - standard output (default)
PETSC_VIEWER_ASCII_INFO_DETAIL - more verbose output for SNESNASM

The user can open an alternative visualization context with PetscViewerASCIIOpen() - output to a specified file.

In the debugger you can do “call SNESView(snes,0)” to display the SNES solver. (The same holds for any PETSc object viewer).
