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++

It should look like this
