Thank you for your reply. I have seen these examples but there aren't examples with C++ code an that's where I have problems (mostly). I have seen the tutorials "How to create a Controller" and "How to do simulation" also, but they are too simple and don't help much. :? For example I have some quest...

Hello there! I try to implement a forward simulation, for example knee flexion (it could be something else for now, I just want to practice some things). Can someone tell me the steps I should follow? For example, should I know the exact forces the muscle produce to move the knee? If yes, how can I ...

Hello,
according to the documentation I think we cannot set geometry path points of a muscle through C++ code.

Can someone tell the steps of how we can set the path points? For example through the XML file of the model or using the GUI?

Cheers,

Hi,
I am new to the subject but as I know so far, it depends on what you wanna do. Usually it's a good approach to take the average values of the parameters. For example, here http://www.wheelessonline.com/ortho/muscle_index you may find them.

Hi James, thanks for responding! Maybe you could answer my question here: https://simtk.org/forums/viewtopic.php?f=91&t=5097 (it's seems that the function bool Ligament::setMaxIsometricForce(double aMaxIsometricForce) sets the same value to the parameter 'pcsa_force': set_pcsa_force(aMaxIsometricFor...

Hello there, you did a great job. I also had many of yours queries so thank you :) In the source code there is this function - look what it does: bool Ligament::setMaxIsometricForce(double aMaxIsometricForce) { set_pcsa_force(aMaxIsometricForce); return true; } so I think we can assume that pcsa_for...

I think you have the same problem as here.

Hi there! i want to create my own cruciate ligament but I cannot understand what this property exactly is: OpenSim_DECLARE_PROPERTY (pcsa_force, double,"force magnitude that scales the force-length curve") (from the source code) When I google "PCSA force" I find nothing, but only PCSA which is not a...

Hello there, could anyone give me some hints on how can I take an .osim file and start with editing it? I would prefer to do it with C++ code because I do not know much about XML. Thanks EDIT: I saw at the OpenSim API: https://simtk.org/api_docs/opensim/api_docs31/classOpenSim_1_1Model.html the func...

SOLVED.

You were right, all i had to do was to erase from the constructor.

But I thought it was just something unnecessary, why should it create such a big trouble?
