Hi there, Hopefully a simple and quick question. I understand that "xfrc_applied" contains a 3d force and 3d torque applied at the center of mass of the body. But what is the "qfrc_applied" to? Is it a torque applied to the joint? Would the indexing be equivalent to the joint indexing? Also, is the torque reported by "qfrc_applied" in Nm? Thanks and all the best, Mike
