TSSetFunctionDomainError

Set a function that tests if the current state vector is valid

Synopsis

#include "petscts.h"  
PetscErrorCode TSSetFunctionDomainError(TS ts, PetscErrorCode (*func)(TS,PetscReal,Vec,PetscBool*))

Input Parameters

	ts	- the TS context
	func	- function called within TSFunctionDomainError

Calling sequence of func

    PetscErrorCode func(TS ts,PetscReal time,Vec state,PetscBool reject)

	ts	- the TS context
	time	- the current time (of the stage)
	state	- the state to check if it is valid
	reject	- (output parameter) PETSC_FALSE if the state is acceptable, PETSC_TRUE if not acceptable

Notes

If an implicit ODE solver is being used then, in addition to providing this routine, the user's code should call SNESSetFunctionDomainError() when domain errors occur during function evaluations where the functions are provided by TSSetIFunction() or TSSetRHSFunction(). Use TSGetSNES() to obtain the SNES object

Developer Notes

The naming of this function is inconsistent with the SNESSetFunctionDomainError() since one takes a function pointer and the other does not.
