# PetscFEPushforwardHessian
Map the reference element function Hessian to real space 
## Synopsis
```
#include "petscfe.h" 
PetscErrorCode PetscFEPushforwardHessian(PetscFE fe, PetscFEGeom *fegeom, PetscInt Nv, PetscScalar vals[])
```

## Input Parameters

- ***fe     -*** The `PetscFE`
- ***fegeom -*** The cell geometry
- ***Nv     -*** The number of function Hessian values
- ***vals   -*** The function Hessian values



## Output Parameter

- ***vals   -*** The transformed function Hessian values





## Notes
This just forwards the call onto `PetscDualSpacePushforwardHessian()`.

It only handles transformations when the embedding dimension of the geometry in fegeom is the same as the reference dimension.


## Developer Note
It is unclear why all these one line convenience routines are desirable


## See Also
