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.
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.
System requirements
What's new in SLFFEA 1.5:
- 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.
