Filename parameters in p.loadSoftBody

[seann999]

Hi, I'm trying to get started with deformable/soft bodies in PyBullet, especially with the (new?) FEM based simulation.
Looking at the usage in https://github.com/bulletphysics/bullet3/blob/master/examples/pybullet/examples/deformable_ball.py, it seems like there are 2 parameters concerning file paths, but the documentation does not mention "simFileName". I would like to know which one means what.
Thank you
