# PetscSectionSetFieldDof
Sets the number of degrees of freedom associated with a field on a given point. 
## Synopsis
```
#include "petscsection.h"   
PetscErrorCode PetscSectionSetFieldDof(PetscSection s, PetscInt point, PetscInt field, PetscInt numDof)
```
Not Collective


## Input Parameters

- ***s -*** the `PetscSection`
- ***point -*** the point
- ***field -*** the field
- ***numDof -*** the number of dof





## Note
When setting the number of dof for a field at a point one must also ensure the count of the total number of dof at the point (summed over
the fields and the unnamed default field) is correct by also calling `PetscSectionAddDof()` or `PetscSectionSetDof()`

This is equivalent to
```none
     PetscSection fs;
     PetscSectionGetField(s,field,&fs)
     PetscSectionSetDof(fs,numDof)
```
