All about tetrahedral elements

This tutorial explores the advantages on using high-order meshes for finite-element modeling of solids using continuum formulations.

Please get the latest version of gmsh2opensees from here.

If you want to use my latest opensees code to run these examples (needed for high-order visualization of stress results) get my OpenSees github fork (10nt-thermal branch) from here. Otherwise comment that function and use the other one for plotting.
