SLFFEA stands for San Le's Free Finite Element Analysis. SLFFEA 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.
SLFFEA includes:
9 of the basic finite element types:
- 3-D 2 node beam
- 3-D 8 node brick
- 2-D 4 node plate
- 2-D 4 node quad (plane stress and plane strain)
- 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
- 3-D 2 node truss
- 3-D 6 node wedge
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.
- Example of brick GUI
- Example of beam GUI
SLFFEA is dedicated to Richard Stallman , Granddaddy of the Free Software Movement, Linus Torvalds, its prodigal son, and everyone on comp.os.linux.setup.

What's New in This Release: [ read full changelog ]
· The double curved shell was expanded to handle triangle elements.
· The 4 node shell element can now handle 3 nodes.
· Several non-linear (large deformation) codes were added and the brick and truss non-linear codes were cleaned up.
· So now it is possible to use the conjugate gradient method as well as dynamic relaxation.
· The following elements now have non-linear counterparts: brick, quad, tetrahedron, triangle, truss, and wedge.
