SLFFEA

Updated 11/27/01

SLFFEA stands for San Le's Free Finite Element Analysis. It is a package of scientific software and graphical user interfaces for use in finite element analysis. It is written in ANSI C by San Le and distributed under the terms of the GNU license.

What SLFFEA includes

14 of the basic finite element types:

3-D 2 node beam
3-D 8 node brick
2-D 3 node plate
2-D 4 node plate
3-D 3 node plate with membrane
3-D 4 node plate with membrane
2-D 4 node quad (plane stress/strain)
3-D 4 node quad with membrane
3-D 4 node doubly curved shell (individual element defined by 4 or 8 nodes)
3-D 4 node tetrahedron
2-D 3 node triangle (plane stress/strain)
3-D 3 node triangle with membrane
3-D 2 node truss
3-D 6 node wedge

1 non-linear large deformation element:

3-D 8 node brick - Updated Lagrange formulation with Jaumann Stress Rate

And 1 thermal element:

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

9 Graphical User Interfaces for each element type:

SLFFEA is dedicated to Richard Stallman , Granddaddy of the Free Software Movement, Linus Torvalds, its prodigal son, and everyone on comp.os.linux.setup .

Electrical Engineers, I need your help!
As you can see, the software I have written is targeted towards mechanical engineering. I have begun a small electrical engineering version based on quad elements. If you are interested in contributing to this project, go here .
