Dear Gmsh community,
I'm quite new to Gmsh and I'm trying to use the recently available OpenCASCADE functionalities. I would like to know if there is a
programatically mean to identify the results of a BooleanFragments operation.
I have two boxes and I would like to cut them with a surface imported as a stp (ShapeFromFile command). So far, my script (attached) works well
in the sense that both of my volumes are cut as expected. I store the output of the BooleanFragments command in a list v() and label each
element in order to control which id number is which volume. I would like to know which volume is above and which volume is below the surface.
For instance, is it possible to return the center of gravity (COG) of a volume
? Based on the COG coordinates, I could identify both volumes.
Kindly,
Lionel
