Eric's MATLAB Stuff  
Stuff here includes MATLAB code for truss and frame structural analysis, and code to rotate any MATLAB plot using the mouse. Actually, the frame and truss analysis are all from the same set of code, cause it's pretty much the same thing. There are three structure definitions, a simple truss, a simple frame, and a not so simple bicycle wheel. Warning! Some of the code is commented better than other parts.

FEMLAB®- Multiphysics in MATLAB  
FEMLAB is a powerful interactive environment for modeling and solving scientific and engineering problems involving partial differential equations. Using FEMLAB, you can build many models by means of the physical quantities involved, rather than the equations describing them. Models developed in FEMLAB can be saved as MATLAB programs for parametric studies or iterative designs.

CUBIT Mesh Generation Toolkit  
CUBIT is a solid-modeler based preprocessor that meshes volumes and surfaces for finite element analysis. Mesh generation algorithms include quadrialteral and triangular paving, mapping, multi-sweeping, tet meshing, and various special-purpose primitives. Our smoothing algorithms are state of the art and are incorporated into volume sweeping. CUBIT contains many algorithms for controlling and automating much of the meshing process, such as automatic scheme selection, interval matching, sweep grouping, and sweep verification. One of CUBIT's strengths is its geometry module, for changing the underlying solid model into the model you wish to mesh. This is now available in library form to other applications, e.g. adaptivity, as the separate "Common Geometry Module" CGM.

THERBOX - Dynamic simulation and analysis of heat transfer in closed environments  
THERBOX performs dynamic simulations of heat exchanges in closed environments. As an agile tool that stands halfway between complex FEM codes and highly simplified analytical models, THERBOX is well-suited for fast preliminary calculations. Conduction, convection, and radiation are taken into account, as is masking due to an object's shape and placement when computing mutual radiation form factors. THERBOX uses simple form objects that can be automatically meshed and interactively placed in the environment. Boundary conditions, such as surface air velocities and temperatures, are stated through simple time-dependent functions.
