Now I'm in trouble in calculating volume of result.
For example, when I did electromagnet field simulation for plasmonic nanoparticle at certain matched wavelength in RF module or wave optics, I could get the electromagnetic field contour map 3d or 2d plane. In this part, when i got 3d electric field contour map, can i get the certain volume in this type of map??? if there is range of e-field 0 to 300, can i get the volume that satisfying my condition selectively like certain range 100 to 200?
If it is possible please explain me.... I 'm newbie in this area... \
Thank you for reading this

Suppose that you want to compute the volume where EXPR is between A and B. Then you can use a Volume Integration feature in Results > Derived Values or Results > Evaluation Group and use the integrand expression
(EXPR >= A) && (EXPR <= B)
There are more advanced variations of this technique that give better accuracy: You can use Filter datasets to extract the volume that satisfies the conditions.

I really appreciate to your kind answer for this question.
I understand what you mean exactly but can you explain more about more advanced variations for better accuracy by using filter dataset?

To measure the volume of the domain where EXPR <= B:
- Create a Filter dataset.
- Set the Expression to EXPR.
- Set Bounds to Upper.
- Set Upper bound to B.
- Create a Volume Integration feature that refers to the Filter dataset, set the expression to 1.
To generalize this to A <= EXPR <= B, use two Filter datasets.

Thanks you for your favor.
Actually now this is the almost first time to doing simulate like this.
Again thank you!
