btSoftBody Internal Forces

[Geometrian]

Hi,

I'm trying to get some kind of measurement of internal forces from btSoftBody. (I need to measure the stress on each link for an engineering simulation. This would also be useful for computing tension in ropes, tearing cloth, etc.)

I have found a few scattered posts, but no answers. I also tried looking at the sources for btSoftBody, but it's not documented enough for me to try calculating it from, e.g. btSoftBody::Link.

How can I calculate some force-like measure on a given link in a btSoftBody?

Thanks,

It has been a while (like many years) looking into btSoftBody, but we are getting back to this and I'll ask someone here to look if this info is easy to expose/extract.
