Once the simulation is done, the solution is stored in fem.sol and can be treated like any old struct. Yup, when femlin() is called, Matlab waits for Comsol to return the data.

Thanks alot.

Then in the Matlab window you run the code above. This method allows you to access the data that the simulation spits out. Alternatively, you can open .m files directly in Comsol, which will run them but won't give you direct data access.<br><br>A useful approach to generating a .m file for a new problem is to generate your model in Comsol and then use the "save as" option to save the model as a .m file, which can then be tweaked and run in Matlab.

I can see that the simulation section is looped. So I suppose that the m-file above is loaded into comsol, to run/solve it? Or is everything done in matlab? Thanks for a great post!

I am also trying to automate a process to solve for the max electric field around a geometry. Was the other script written to automate the process in Matlab or COMSOL? This is a great write-up.
