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
download a mesh description from github.com/feelpp/feelpp/
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

To run this example,
mpiexec -n 4 python3 test_exporter.py
The location of the results are shown in the output of the script.

It remains to open the file
