Hi team, I am trying to do a forward dynamic simulation of gait10dof18muscle model. I removed/disabled the muscles in the model and was trying to run the model with reserve actuators in CMC. Once I get the controls for the gait, I tried using them in the forward dynamics with same reserve actuators....

I have been using the OpenSim 4 beta version and the osim files were generated as <OpenSimDocument Version="30516"> as a result of it. Now, I downloaded the latest release of OpenSim4 and am not able to load the files generated by opensim4 beta. It gives me the following error: https://image.ibb.co/...

There is a tutorial on performing ID using the external loads. Please have a look at it https://simtk-confluence.stanford.edu/display/OpenSim/Part+II%3A+Leg+Muscle+Force+Estimation+in+Stance An excerpt from the tutorial explains what each columns represent : Force Columns: select "ground_force_vx" f...

You may wish to refer to the "The Strength of Simulation: Estimating Leg Muscle Forces in Stance and Swing" example in the Confluence documentation ( https://simtk-confluence.stanford.edu/display/OpenSim/The+Strength+of+Simulation%3A+Estimating+Leg+Muscle+Forces+in+Stance+and+Swing ). See, in parti...

Hi, I am trying to figure the "proper/recommended" workflow in using RRA to proceed with a model suitable for performing CMC, SO and forward dynamics. I am following the user guide https://simtk-confluence.stanford.edu/display/OpenSim/Getting+Started+with+RRA but a still confused with how to proceed...

I renamed the joints in the .osim file from "hip_r" to "hip_r_0" and did this for knee and ankle left and right too. This resulted in the scale factors filling in for the femur, tibia and talus and allowing the option for scaling to run. Looking at the weights I see that the translation coordinates...

You can use the analyze tool, provided the state from CMC. You have to add a MuscleAnalysis, which exports the moment arms. Thank you :) In the advanced option of the plotting tool you can change the range of the coordinate. Sorry, I think I didn't explain the problem clearly. You can see that the ...

Thank you Dimitar. Yes you are right. For now I have been calculating the moments the same way as you mentioned. I plotted the moment arms and then exported the data to a separate file to do moment calculations. As I get forces, activation and joint angles after executing CMC. Is there any way to ge...

Hi team, I have been using the plot tools as well as the .sto files generated after performing analysis like RRA and CMC to view results such as joint angles and forces. I am having a bit of trouble to understand how the plotting tool works in OpenSim. Consider the case where I run CMC for a gait239...

Hi, I loaded the gait2392 model from the Resources folder that is available in the OpenSim default installation. After making a few changes in the model in GUI(OpenSim4) I saved the model to a new osim file. It looks very different from the earlier one. I was interested in finding the tag <location_...
