SNESTSFormFunction

Function to evaluate nonlinear residual

Synopsis

#include "petscts.h"  
PetscErrorCode  SNESTSFormFunction(SNES snes,Vec U,Vec F,void *ctx)

Logically Collective on SNES

Input Parameter

	snes	- nonlinear solver
	U	- the current state at which to evaluate the residual
	ctx	- user context, must be a TS

Output Parameter

F

- the nonlinear residual

Notes

This function is not normally called by users and is automatically registered with the SNES used by TS. It is most frequently passed to MatFDColoringSetFunction().
