I have enjoyed a considerable boost to my own work from
several open source projects over the years, and I
also have made the libraries and toolkits that I designed myself
available to others. Open source works!
The material on this page is intended to be an
educational resource for undergraduate or graduate courses
of finite element analysis, for mechanical, chemical, civil, and other engineering
students. You will find
here a
software toolkit for Matlab. The software is
available as open source.
By
making these resources available to everyone, I'm hoping to be
able to collect feedback and suggestions that will enhance the usefulness of this material for everyone.
The
software is protected by the GNU
General Public License.
For the software, any ideas, suggestions, and design insights are welcome.
I will decide whether I'm going to include any modifications in my version of the toolkit,
which is going to be available from this web site. You, on the other hand,
have the freedom to work any modifications into your own version of the toolkit.
The next update will include contact and more hyper elasticity examples. As usual,
corrections and improvements will be posted if and when needed.
A number of bug fixes. Improvements to a number of meshing functions,
including meshing (coarsening) of 3-D images.

Minor changes and updates. Additional meshing functions. Call for the change log in documents/Changes.m.
Minor changes and updates (graphics_viewer class). Additional meshing functions. Additional meshing examples (surface meshing). Call for the change log in documents/Changes.m.
Cleanup of graphic_viewer class, and a few changes in feblock_defor_ground. Call for the change log in documents/Changes.m.
Update to the subset and get methods of the gcellset_beam3 class to correctly handle access to all attributes. Additional methods for the @feblock_defor_ss_corot_beam class. Cleanup of image_meshing examples (the AVWTk toolkit is needed to run these examples). Call for the change log in documents/Changes.m.
gcell_select enhanced with the option to search for the cell nearest to a given location (nearestto). Corrected logic in the method set_ebc() of the Field class. Revised physical_units().
