SLFFEA 1.5

San Le's Free Finite Element Analysis
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:
  • 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.
