Papers discussing TET4 elements generally address the following characteristics:
: Despite accuracy issues, TET4 is popular because it allows for easy and robust automatic meshing of complex 3D geometries. Relevant Academic Literature tet4.rar

: TET4 elements can only represent a constant strain state, which often requires a very fine mesh discretization for accurate results. tet4.rar
: These elements are known to "lock" (over-stiffen) when simulating nearly incompressible materials or bending deformations, leading to results that underestimate true solutions.
