# SNESSetCheckJacobianDomainError
tells `SNESSolve()` whether to check if the user called `SNESSetJacobianDomainError()` Jacobian domain error after each Jacobian evaluation. By default, we check Jacobian domain error in the debug mode, and do not check it in the optimized mode. 
## Synopsis
```
#include "petscsnes.h"  
PetscErrorCode SNESSetCheckJacobianDomainError(SNES snes, PetscBool flg)
```
Logically Collective


## Input Parameters

- ***snes -*** the SNES context
- ***flg  -*** indicates if or not to check Jacobian domain error after each Jacobian evaluation





## Note
Checks require one extra parallel synchronization for each Jacobian evaluation
