Hi COMSOL forum!
I am currently working on a Solid Oxide Fuel Cell (SOFC) simulation. I am looking for a way to calculate a "volume of a certain region which considered inside the data range".
I attached the picture of my current problem.
Thank you and regards, Perdana - Student of engineering

I suggest you integrate a Boolean expression across a larger volume that includes the volume of interest to you. You need to set up your Boolean expression to evaluate to 1 (aka, true) wherever the quantity of interest to you falls within the desired range of values, and 0 (aka, false) wherever the quantity of interest to you falls outside of the desired range of values. Integration can be done via post-processing under Results, or can be set up as a probe.

Robert's advice is the right solution in 5.3a.
In 5.5 and 5.6 you can get a more accurate result by creating a Filter dataset that extracts the region of interest and integrating 1 over the Filter dataset.
