COMSOL Multiphysics also offers an extensive interface to MATLAB and its toolboxes for a large variety of programming, preprocessing and postprocessing possibilities. The packages are cross-platform (Windows, Mac, Linux, Unix.) In addition to conventional physics-based user-interfaces, COMSOL Multiphysics also allows for entering coupled systems of partial differential equations (PDEs). The PDEs can be entered directly or using the so called weak form (see finite element method for a description of weak formulation). I am a college sophomore with a dual major in Physics and Mathematics @ University of California, Santa Barbara. By the way, i came across these excellent <a href="http://www.funnelbrain.com/" rel="nofollow">physics flash cards</a>. Its also a great initiative by the FunnelBrain team.

I had memory issues in begining but then I contacted the comsol guy and they suggested me to use iterative solver and also they suggsted me to use the solver independetly. As the model has two modules so its possible to select in solver setting to solve for and store the solution and then solve for the next module using the previous solution. Which helped and I didnt have any memory issues after that. I hope that helps.C2EC- Swanseahttps://www.blogger.com/profile/03531253323807413926noreply@blogger.comtag:blogger.com,1999:blog-8085067644078822297.post-1303557302732084822006-11-07T09:22:00.000-08:002006-11-07T09:22:00.000-08:00Hi,

In the 3D model looks like you have drawn all the wires, however in the 2D model looks like a foil conductor.
