Can one program Comsol to iterate through the physics of a model?

I have an electrode stack and need to solve for the potential at each one of the 37 electrodes when only one is powered while the rest aren't. That is, Enable electrode 1 at 1V, the rest of the electrodes disabled, solve, export data as .txt Enable electrode 2 at 1V, disable previous electrode, solve, export data as .txt . . . I would have to do this 37 times, when each computation takes ~14 mins. Is there a way to let COMSOL running with this iteration or is this the essence of COMSOL's manual labor?

Hi Dalila,
There are two types of answers to your question. For the general case, you can use a Model Method. You could also use scripting through Matlab or the Java API.
You can find some instructive texts about model methods on our blog, for example

and

For AC/DC in particular, there are however special methods for setting up sweeps over boundary conditions. Seach for 'sweep' in the AC/DC module documentation.
