Hi
One can use the 'measure tool' to calculate the area of any 2D geometry in COMSOL.
I want to know how to do it programmatically in COMSOL.
In my application, I need to use a parametric sweep to calculate, for example, the area difference between a circle and a square over a range of circle radius and square side.

Hi Ravinder,
if I understood correctly, the best way would be to run a prametric sweep changing the radius of the circle and then do the following:
Under the result section, select:
- derived values--> surface integration
- Add expression --> model --> geometry --> dom entitity index
This expression computes the area of the selected surface for each geometry of the parametric sweep.
Is this what you are looking for?
