BLZ2T
Plane or axisymmetric state
Description
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
