TSAdaptCheckStage

checks whether to accept a stage, (e.g. reject and change time step size if nonlinear solve fails)

#include "petscts.h" 
PetscErrorCode TSAdaptCheckStage(TSAdapt adapt,TS ts,PetscReal t,Vec Y,PetscBool *accept)

Collective on TSAdapt

	adapt	- adaptive controller context
	ts	- time stepper
	t	- Current simulation time
	Y	- Current solution vector

accept -PETSC_TRUE to accept the stage, PETSC_FALSE to reject
