# PetscFEGetHeightSubspace
Get the subspace of this space for a mesh point of a given height 
## Synopsis
```
#include "petscfe.h" 
PetscErrorCode PetscFEGetHeightSubspace(PetscFE fe, PetscInt height, PetscFE *subfe)
```

## Input Parameters

- ***fe     -*** The finite element space
- ***height -*** The height of the `DMPLEX` point



## Output Parameter

- ***subfe  -*** The subspace of this `PetscFE` space





## Note
For example, if we want the subspace of this space for a face, we would choose height = 1.
