Hi all,
I have a 3D geometry and I was trying to get the boundary area of certain portion as an input for the further calculation.
As suggested, there are two ways to get the area value: 1. Use measure under the geometry tag to get the boundary area. 2. Use intergration function for this boundary (such as expression intop(1)) to get the area.
However, I found the values from these two method are a bit different. For example, for a circular plane, from integration method it got 9.7193E-12 [m^2], but from the measure methode it showed 1.0169E-11 [m^2]
Why there is a difference? And which one should I trust?
Thank you
