# PCHYPREAMSSetInteriorNodes
Set the list of interior nodes to a zero-conductivity region for `PCHYPRE` of type ams 
## Synopsis
```
#include "petscpc.h" 
PetscErrorCode PCHYPREAMSSetInteriorNodes(PC pc, Vec interior)
```
Collective


## Input Parameters

- ***pc -*** the preconditioning context
- ***interior -*** vector. node is interior if its entry in the array is 1.0.





## Note
This calls `HYPRE_AMSSetInteriorNodes()`


## Developer Note
If this is only for  `PCHYPRE` type of ams it should be called `PCHYPREAMSSetInteriorNodes()`


## See Also
