Operate with the solutions of a parametric sweep simulation

Hello

I have solved a problem using the parametric sweep simulation. Now, of course, I have a result for echad parameter, now, what I want it is sum all of these results, what I do not how to do it...


I do not want to export a text file for each parameter and then make the sum (for example with matlab), because I want to use the results for use them with comsol.

Do you have any idea?

Thanks
