# Exporting results for visualisation

We now turn to the exporter facility of Feel++ which allows to provide the results of Feel++ solves in a format readable by ParaView or EnSight.

In this 2D and 3D example, we

• build the mesh and partition it

• build a function space $X_h$

• create an element $u$ of $X_h$ which interpolate an expression givn by the end-user

• export to the Ensight Gold format (the default Feel++ format) of Feel++

Example to build a mesh and function space, create an element and visualize them in ParaView
``404: Not Found``

To run this example,

``mpiexec -n 4 python3 test_exporter.py``

The location of the results are shown in the output of the script.

Output of the script
```[ Starting Feel++ ] application test_exporter.py version 0.1 date 2021-Jul-16
[feelpp] create Feel++ repository "/home/saigre/feelppdb" ...
[feelpp] create Feel++ geo repository "/home/saigre/feelppdb/geo" ...
[feelpp] create Feel++ exprs directory "/home/saigre/feelppdb/./exprs" ...
. test_exporter.py files are stored in /home/saigre/feelppdb/./np_4
.. logfiles :/home/saigre/feelppdb/./np_4/logs
It remains to open the file `.case` with ParaView or EnSight.
