SNESNewtonALSetDiagonalScaling

Set the global vector used to rescale DoFs for computation of arc length.

Synopsis

#include "petscsnes.h" 
PetscErrorCode SNESNewtonALSetDiagonalScaling(SNES snes, Vec v)

Logically Collective

Input Parameters

• snes - the nonlinear solver object

• v - the Vec containing diagonal scaling for each DoF, must be the same size as the solution vector (may be NULL)

Note

This function stores a reference to v. Any changes to the vector will be reflected automatically in the arc length computation.
