====== BLZ2T ======
Plane or axisymmetric state
===== Description =====
{{  :elements:blz2t.png?300|}}
Element for thermo-mechanical analysis in large deformation with or without metallurgy (static or dynamic). \\
\\
For the axisymmetric element, the symmetry axis is Y. \\ \\
The element is defined by 4 nodes specified in NODES(4) following the order given in the figure. \\
\\
Type: 208 \\
Implemented by: Y.Y. Zhu, 1991
