Microgravity experiment

[Tuhin Sengupta]

I am new to OpenSim. I have two doubts-
1) How to change the thickness of bone which is a similar case to osteoporosis.
2) How to change the gravitational settings in OpenSim. Changing it to 0m/s for microgravity simulation.
Regards

Hi, Tuhin-

1) How to change the thickness of bone which is a similar case to osteoporosis.

There is no concept of bone thickness in OpenSim. The bones you see on screen are for display and guidance only. Often, people will perform an OpenSim simulation to get joint contact and muscles forces then import those to a Finite Element Analysis simulation for bone stress.

2) How to change the gravitational settings in OpenSim. Changing it to 0m/s for microgravity simulation.

Gravity is defined in the model file (.osim). You can open the model file in a text editor and change directly.

Is there a 3D model of real bone which OpenSim models (e.g. femur in gait2392 / gait2354) work with?
If yes, where could it be found?

I wanna use scale it to my CT-based patient-specific bone in advance.
Thanks.
