Does anybody know how to access physical sim data, such as edge/vertex loads, etc.?

Hi all,

I’m trying to do some advanced sim in blender physics, and can’t figure out how to access load data, etc. For example, if I have a ball colliding with a wall, I’d like to access and directly modify the forces in the ‘edges’ or nodes using a python script… anybody know where this data is? Or if t can be accessed and modified?
I want to add time-dependent behavior to the spring forces to make an object deform in non-standard ways (for integrating with FEA calculations or other external physics calculations).

thanks in advance.
