add an option #360

In reinforced concrete section, can you add an option: Do not subtract the area of steel in the concrete.Because, in the specification calculation formula, the area of the concrete part occupied by the steel bar does not need to be deducted.Thanks.

Thanks for opening your first issue in sectionproperties :raised_hands: Pull requests are always welcome :wink:

Hi @jiandong-qiao, thanks for your question. sectionproperties uses the finite element method to calculate cross-section properties and relies on generating a mesh. Unfortunately, the library we use to generate the mesh, triangle, does not support elements stacked on top of one another. While it would be possible to create this geometry with the pre-processor, the meshing algorithm would just end up subtracting the concrete area. As a result, this is not currently an option that can be supported.
