Hi there, > more advanced numerical computations (e.g. in Finite and Boundary > Ellements) is better to use other systems or programming languages. For the finite elements have a look at http://www.imtek.uni-freiburg.de/simulation/mathematica/IMSweb/imsTOC/Application%20Examples/Finite%20Element%20Method/index.html Please do not forget that with Mathematica you are able to _generate_ the C code you might want to have if the performance is not good enough. I found that Mathematica in the combination with the IMS is well suitable for systems of equations of about 50K degrees of freedom, but we have gone up until 500k degrees of freedom - of course this is not too much compared as to what you can do in C (or Fortran etc) but not every problem needs as many degrees of freedom ;-) and, as mentioned, the C code generation can surely be automated. Also the time needed to implement a new feature is probably shorter than in a compiled language. Regards, Oliver Oliver Ruebenkoenig, <ruebenko at imtek.de> Phone: ++49 +761 203 7388
