Hi,

I am trying to compute the integral of two different modes which are from different geometries. Currently, I am saving the model files separately for each geometry and using mphinterp twice on a grid to compute the integration. Is there any way to use mphint directly to save computation time?

I tried to make a file with two different geometries and using mphint, but I can't get it to evaluate from both solutions at the same time.

Thank you,

Martin

Hi

Do you need to calculate the integral in Matlab ?

Otherwise you could define an integration operator in Comsol and get the result via 'mphglobal' on two different dataset, pointing to each of your solutions in the model.

The integral does not need to be done in MATLAB. The integral is an overlap between two modes and if I look at the integration available in the derived results, I have to choose either of the datasets, while I am looking to integrate mode1*mode2 over the surface. Is there some integration operator that let me take variables from different datasets in the same evaluation?

Hi

have you checked the specail operators at() and with() I believe these can be used, but in the Postprocessing though

Good luck
