# PetscSectionLoad
Loads a `PetscSection` 
## Synopsis
```
#include "petscsection.h"   
PetscErrorCode PetscSectionLoad(PetscSection s, PetscViewer viewer)
```
Collective


## Input Parameters

- ***s -*** the `PetscSection` object to load
- ***v -*** the viewer





## Note
`PetscSectionLoad()`, when viewer is of type `PETSCVIEWERHDF5`, loads
a section saved with `PetscSectionView()`. The number of processes
used here (N) does not need to be the same as that used when saving.
After calling this function, the chart of s on rank i will be set
to [0, E_i), where \sum_{i=0}^{N-1}E_i equals to the total number of
saved section points.
