converting COMSOL code to the MATLAB ???

Hello,

I'm working with COMSOL to simulate a chemical experience, but it takes too much time to display the results.
So i want to find a link between comsol and matlab if i can convert the code of comsol to matlab that will be faster than using comsol alone !!!
So am asking if i can do this and how ????


watting your answer
thank you very much :)

Re: converting COMSOL code to the MATLAB ???

here are the steps:

Step in Comsol:
- save model as .m

Start 'Comsol with Matlab'

Steps in Matlab:
- open the .m
- put first and last lines of the code in comments:
% function out = model
...code...
% out = model;
- at the end of the code, insert lines to extract results, here is an example for heat transfer, see the docs for mpheval:
T = mpheval(model,'T') % temperature
kx = mpheval(model,'ht.kxx') % thermal conductivity in x
- Run your .m (F5) and see the extracted data in the matlab workspace
- The postprocessing world is yours!
