In material properties we can change the parameter stiffness to customise ground properties. My question is this unit "stiffness" is "coefficient of restitution" ? If yes, then is there any chart to see to relate the data for hard and soft ground? If no, what is the unit of the "stiffness" parameter...

Hi, I am trying to create a model from H0914M, to include 5 Hunt Crossley sphere contact at the feet. I have been successful to do so by simply editing in VS-code. I am attaching it below. I added, rm_heel,rmm_h, and rmm_h as separate objects depending on location, and radius. The same changes have ...

Hi,
I am facing a problem where the Matlab is not recognising the Model keyword in Model('../Model/WalkerModelTerrain.osim');
I have earlier used this and it worked. However, right now it is not working. Any help on what might be the reason?

Thanks a lot. One doubt, How many contact points are in the scone model(feet) when it is touching the ground throughout the simulation? Also, Is there any parameter where I can change the type of platform type?

Thanks a lot. One more doubt though.
What parameter should I change to obtain data of any model walking/jumping for 60 sec in the real world? Also, What does the x-axis of the data represent in GRFs(others too)?

Hi, I have some doubts, I can not seem to find answers on my own, 1. I want to change specific parameters like the duration of the walk (not simulation). What parameter will increase the duration of GAIT (suppose for 2 minutes )? Will this make the optimisation take more time? In this case, Hyfydy w...

Hi,
This is exactly where I am struck.
Where do I get the initial conditions ? Is there any template files available?
Please suggest.
Thanks

In Dynamic Walker Challenge, I have built the model step-by-step as shown in the tutorial. However, the model is not walking. It is falling behind. I have done forward simulation(0-2s) as shown, still the model is not walking. I have run the Designmainstarter.m script it is not walking. I think I ne...

Hi,
I am new to opensim. I downloaded and installed the .exe file. However, it does not shows any menu or anything. It only shows window and sub category of tools and output.
I have uninstalled and installed multiple times.
Please guide what I am doing wrong.
Thanks,
Mainak

Thanks a lot for the reply. I got the .sto file.
