I first converted the initial .stl mesh to a .msh and loaded it in a view via the PView->readMSH function. When I ran Tetrahedralize on this view (PluginManager::instance()->

Plugin(Tetrahedralize) directly uses as input a post-processing view containing point values.

So just load a .pos file with data points and run Plugin(Tetrahedralize); that's it.
