How to create segments on an irregular geometry

[jmbtin001]

I have an irregular geometry that can be approximated as an ellipse with shown in this link : https://www.researchgate.net/figure/a-T ... _221512313

I would like to divide this geometry into segments. The height will be divided into three equal portions. Each portion will have equal segments around the ellipse. I would also like to be able to obtain post processing data for each of this segments. How may i be able to implement this?

If do you have a CAD model of your shape, created with NURBS then can divide it in parametric directions u or v
with
Geometry->Edit->Divide->Surfaces
(num divisions, or near point or parameter)
-num divisions simply divide in n parts in space parametre
-near point will calculate the u,v parameters from a 3D coordinate (u,v that minimize the distance from the parametric surface to this coordinate)
-parameter you directly set the parameter value (from 0.0 to 1.0)

And similar to divide Curves, in this case there are also options 'Relative length' and 'Length' to do the cut at t parameter of the wanted 3D curve length.

You can use meshing software like Gmsh or ANSYS to divide the geometry into equal segments. Define three height sections and apply structured meshing around the ellipse. For post-processing, assign element sets or regions for data extraction.
