# SNESFASFullSetTotal
Use total residual restriction and total interpolation on the initial down and up sweep of full FAS cycles 
## Synopsis
```
#include "petscsnes.h"  
PetscErrorCode SNESFASFullSetTotal(SNES snes, PetscBool total)
```
Logically Collective


## Input Parameters

- ***snes -*** the `SNESFAS`  nonlinear multigrid context
- ***total -*** whether to use total restriction / interpolatiaon or not (the alternative is defect restriction and correction interpolation)



## Options Database Key

- ***-snes_fas_full_total -*** Use total restriction and interpolation on the initial down and up sweeps for the full FAS cycle





## Note
This option is only significant if the interpolation of a coarse correction (`MatInterpolate()`) is significantly different from total
solution interpolation (`DMInterpolateSolution()`).


## See Also
 `SNESFAS`, `SNESFASSetNumberSmoothUp()`, `DMInterpolateSolution()`

## Level
advanced
