This is also my understanding too. We have not tested it to any great extend and so typically rely on extruding the 2D meshes to make a 3D mesh currently. @Giacomo: Who was the student at Southampton who was further develop this solver. Possibly we should check with him and see if he has an updated branch. I am cc’ing Zhen-Guo since I recall he was a friend of Zhen-guo. Cheers, Spencer.
