Post-processing and integration of multiple solutions
Hi,
I would like to integrate a Expression that involves variables from several different solutions obtain in a single application mode.
Second is doing a integrate an Expression what involves variables from two application modes but each has several solutions.
Is there a way to choose a specific solution (determined by parametric solver) from each mode and do an integration over a boundary?
I can find out the value for each expression for a given boundary using postinterp. However, I get values so integrating smoothly becomes a bit of a problem.
I know there is the function postint, but I don't know if this can call a specific solution number in several application modes.

Re: Post-processing and integration of multiple solutions
Hi
I believe you have the variable "'solnum',n" for your "post..." commands in matlab, but if I remember right these have different meaning depending on the application mode settings (eigenvalue, parametric, harmonic, transient ...)
you have also the "at(12.5,u)" operator when you want to use a specific time tag value here for "u" in your comsol euqations, the "'solnum',n" varable has the "with(3,u^2)" operator ( here for "u^2" see the command.pdf doc)
If your solutions are from different runs you set up, I believe you must use matlab and store the different solution as fem1, fem2 ... and integrate in a loop within matlab
Good luck
Ivar
