How to turn off muscle physiology in Static Optimization
Hi, Can I ask how to turn off the use of muscle physiology during the static optimization please? I've tried both Api and GUI to toggle off the use of it, but I still constantly got the error message about some muscles unable to equilibrate. I'm using the latest version 4.4, not sure if this is the ...

the knee reaction force during squat
Hi, there. Can I ask if someone tested the human knee reacion force during squat or ever used he data from Grand Challenge Competition to Predict In Vivo Knee Loads? I want to use experiment data to compare with my FEA analysis result, but found the data (screenshot below) from Grand Challenge Compe...

the problem of recognising local frame during joint reaction analysis
Hi, there. I am trying to use joint reaction analysis to get the ankle forces and moments. In the settings, there is one to input the frame name in 'express_in_frame'. However, whenever value, for instance, 'ankle_angle_l' or 'knee_angle_l' in the <Coordinate name=>, the output result always gave th...

the problem of applying Mesh Geometry to the non-conformity contact pair
Hi, there. I want to use the mesh geometries of self designed total knee replacement (non-comformity) to predict knee forces. I have successfully calculated the Inverse Kinematics, Residual Reduaction Algorithm and Computed Muscle Control without consideration of mesh geometries. However, when it ca...

how to filter the EMG data from grand challenge competition to predict knee loads
Hi, there.
Anyone knows how to filter the EMG data? I saw some one mentioned the butter function in matlab. if so, which cutoff frequency and sampling frequency should I use?
Thanks,
Linjie

Re: muscle length measure and its parameter setting
Hi, Chris.
Do you mind if I ask the journal paper that referred to the musculotendon parameters for the JW model as the linked paper you just sent? Unforunately I have tried to find it for a long time.
Many thanks,
Linjie
