The Nonlinear Finite Element Toolbox (NLFET)

NLFET is a nonlinear finite element toolbox for MATLAB released under the GNU General Public License (GPL). The toolbox provides a framework for setting up, solving, and interpreting results for nonlinear static and dynamic finite element analysis.

Manual - A short overview of NLFET in PDF format.
Download - The source code for the toolbox in tar gzip format (WinZip should be able to extract this).

Single Bay Example - Example code using the single bay frame from "A Nonlinear Finite Element Toolbox for Structural Control" presented at the Third World Conference on Structural Control.
util.tgz - Utility functions in tar gzip format that are necessary to get the toolbox to run and for the examples.

Example code for a semiactive control system using MR dampers is also available. Please contact info@nlfet.org if interested.
