problem with the contact geometry definition
Posted: Wed Apr 19, 2017 3:58 am
Hi, there.
Is there anyone could help me?
Recently I built a knee joint musculoskeletal model in openSim, and trying to use the setting of triangular mesh volume (.obj) to define the contact relationship of knee joint. However, when I added the contact force in the forceset of osim file and ContactGeometrySet just as the attachments below, my contact geometry pair (left bottom one in the first screenshot) couldn’t be overlaid with my knee joint musculoskeletal model (right hand one). No matter how I changed the body name in the properties of Contact geometry (I guess the body name here is the local reference frame), the location and orientation of the contact geometry just didn’t have any change. So I am wondering if I misunderstood the local reference frame of the contact geometry or the setting I did is incomplete.
Thanks in advance,
Linjie
