Using the plot tool of Opensim1.5.5 and opensim3.3 to draw out the sum of moment about all the muscles actuators about the right knee.the result of Opensim1.5.5 is -3 ~ 4, the result of Opensim3.3 is -43 ~ 56, and the model and movement are exactly the same, The results should have been the same. So...

A is obtained through Opensim3.0,, B, C is obtained through Opensim1.5.5, they were used the same data and settings files to plot, why the difference is so big, what is the reason of the phenomenon，thanks~

Hello： M = I * a ，a is the angular acceleration generated by the joint angle calculation, I is inertia，in order to obtain the curve of I change, which moment should be used in the following three, A) Joint moment= tendon force (each muscle) * moment arm (each muscle) B) the sum of muscles'moment in ...

There are some problems again~ 1. F * moment_arm = moment, where F is the force of each muscle, and what is the relationship between this Force and plot total fiber force. when moment is the sum of muscles’moment，moment _arm is the sum of muscles’ moment_arm, and What is the force’s physical meaning...

I have read the guidance of user, but there are still some problems： Question 1: want to get the starting and ending coordinates of the muscles, and then get the existing model of the exact direction of muscle, x、y、z data of fixed、via,、moving point Is offset? Not the starting and ending coordinates ...

For this part of the content, I have read before, but still do not know a series of vertical coordinates of the plot tool is incremental data, or the length after the change, if I want to draw the joint moment diagram, whether it can be directly selected Y moment -knee_angle, select extend and bend ...

Hi: When I use the plot tool of Opensim, There are many lists, such as moment, moment arm, fiber length ,muscle tendon length, total fiber force, tendon length, tendon force and so on. I can think of them by literal meaning，but I want to get the moment of the knee，only to Calculate the sum of the mu...

I recently analysis the human lower limb ,Through the study of the experimental data GIL series about May Liu's walking study in the Stanford Web site , I want to get the joint torque curve in Figure 2 in paper named 《Muscle contributions to support and progression over a range of walking speeds.》 S...

The experimental data in the figure is the shaded area data, the simulation result is black line, and the simulation data is finished by which tool in the opensim, how can I get the curve ? thanks a lot ~~~

There are also have some questions： 1.The Data is insufficient, the original data packet is only about 90% of the gait data; 2.the trend of GIL04 is highly different with other curves, is there a data modification method？3. on the basis of 90% of the data ，Draw each experimental curve, Spline interp...
