Hi Karol,

Thanks very much for your sharing.

As described in the code:
branch = b1->state->pos - b2->state->pos;
stressTensor += (nsi->normalForce + nsi->shearForce) * branch.transpose();

Based on my limited knowledge of cpp, I think the brach vector is
calculated by the position of the two objects, no matter they are sphere
or wall. Please correct me if I am wrong.

Best,
Leonard
