Currently tetgen is the limiting factor here as well, it can produce subparametric second order elements, but wouldn't support producing elements that conform to an existing second order mesh. If we wanted to use a second order mesh, we would have to turn it into a first order mesh, vacuum mesh everything, and then add the mid nodes back in, thus losing a lot of information in the process. I'll see if any solutions exist to help with this.
