Sure, that’s the way I usually do, and I use Cleaver over Tetgen as well.

For the EP modelling I use [Chaste](http://www.cs.ox.ac.uk/chaste/). It uses Tetgen format, so after mesh generation (using Segment Mesher) I convert resulting |.vtk| file into |.node|, |.ele|, |.face| files using script provided with Chaste.
