Using API to Delete Elements from a Truss That Have Highest Compressive Stress

Hi everyone,

I am a complete beginner to API and need help. I am doing an experiment and my model is a truss with a lot of members (hundreds of them). I need to run the program, then take the element/elements with the highest axial compressive stress (Fx/Ax) and delete them. Then run the program again with the same loads and delete the elements with the highest axial compressive stress and so on. I could do it manually but since my model has a lot of elements, this could take a very long time.

Is it possible to do this using API, given the model geometry, supports and loads are already defined within Robot? If so, could someone please show me how it could be done using Excel VBA? I would very much appreciate it.

Many thanks
