3. 2-D 3 node plate
4. 2-D 4 node plate
5. 3-D 3 node plate with membrane
6. 3-D 4 node plate with membrane
7. 2-D 4 node quad (plane stress/strain)
8. 3-D 4 node quad with membrane
9. 3-D 4 node doubly curved shell (individual element defined by 4 or 8 nodes)
10. 3-D 3 node doubly curved shell (individual element defined by 3 or 6 nodes)
11. 3-D 4 node tetrahedron
12. 2-D 3 node triangle (plane stress/strain)
13. 3-D 3 node triangle with membrane
14. 3-D 2 node truss
15. 3-D 6 node wedge

6 non-linear large deformation elements using Updated Lagrange formulation with Jaumann Stress Rate:

1. 3-D 8 node brick
2. 2-D and 3-D 4 node quad
3. 3-D 4 node tetrahedron
4. 2-D and 3-D 3 node triangle
5. 3-D 2 node truss
6. 3-D 6 node wedge

And 1 thermal element:

1. 3-D 8 node brick - It can handle thermal loads as well as orthotropy.

9 Graphical User Interfaces for each element type:

1. Example of brick GUI
2. Example of beam GUI
