Hi all
I was wondering how to get hunt-crossley contact force from inverse dynamic tool. Pleas let me know if how to get it.
I will want to use matlab to get it.

Hello my friends I was wondering if how can receive the kinematic of every point in musculoskeletal model. for example, I want to know the position and velocity of the calcn in simulation. How could reach it? Actually, I use the following code, but it's not correct. import org.opensim.modeling.*; HG...

Hi Dears
I was wondering if how can give metabolic cost of human walking in opensim? is it done by CMC? How?

thanks to answering me

Dear Friend
I run CMC tool while setup files are in same location including:
gait2354_simbody
gait2354_CMC_Tasks
subject01_walk1_ik
subject01_walk1_grf

but this error is displayed:

Hi guys I'm gonna to simulate CMC tool in opensim by data C:\Users\user\Documents\OpenSim\4.1\Models\Gait2354_Simbody. I get following inputs: Desired kinematics: subject01_walk1_ik.mot Tracking Task: gait2354_CMC_Tasks.xml then run . but this error is displayed. what's the problem? inputs.PNG error...

Hi guys
if we want to drive forward dynamic for skeletal human body, How could be record the muscle activity of human gait? Actually, If the skeletal model is used, we couldn't get any muscle activity to determine this solution is correct for reducing the human effort?

Hi friends Recently, I was wondering if I can actuate lower limb joints to drive skeletal model. In fact, I tried to drive the skeletal human body by forward dynamic in closed loop. Now I want to know that the human model could be balanced only by lower limb joints(hip-knee-ankle )? In detailed, the...

Hi Guys

I was wondering if how to get the kinematic and dynamic equation of human body used in OpenSim.
Actually, the dynamic equation is yield by Euler-Lagrange Theory.

Thanks so much

Hi everyone i was wondering if how get a osim model that is included joint trajectory (motion) and contact force (huntcrossly force parameters). the gait2392_simbody is a complete model that have grf information but the huntcrossly contact (parameters) is not included. so Please me guide to how get ...

Hi everyone I want to get a point position, velocity and acceleration. So i use this code in matlab: nn = HGait.PointKinematics; nn.setBody(HGait.updBodySet.get('tibia_l')) R = Vec3(0,0,0); nn.setPoint(R) nn.setPointName('yf') nn.getAccelerationStorage() but this is not yield the values of accelerat...
