Hello Ayman,

Yes, it was helpful for me. When I delete the of GenericModelMaker, I did not see any errors. The scaling operation was also done properly as I saw with GUI-tool.

Thank you,

Hello,

I realized that marker data should be separated from model data. When I merged marker data into osim model file, scaling tool was failed in script. But GUI-based Scale tool works with merged osim file.

Now, I found my solution.

Thank you,

Hello, I have similar experience with ScaleTool. Recently, I downloaded the latest OpenSim ver.4.1 and tried to analyze gait motion database with more than 100 subject data. Because of many subject data, I really wanted to run overall process from scaling to estimating muscle activities in automatic...

Dear experts, I'm trying to simulate a pulling cable with take-up machines. Servo motors on the take-up machines usually control positions and velocities. So, I'd like to express cable tensions based on roll length. I checked previous discussion on the forum: https://simtk.org/plugins/phpBB/viewtopi...

Hi Dimitar! Thank you for your response. Yes, I made a double check with both of GUI and ForceReporter outputs. I changed realization from acceleration to dynamics stage, but get force does not give me any outputs. I remember you used generalized force data for task space control. How did you monito...

Dear Experts, I have a question about getting method of contact force data through C++ OpenSim API. I used something like: osimModel.realizeAcceleration(si); auto vals = osimModel.getForceSet().get(ContactForceName).getRecordValues(si); However, obtained values show always zero even the contact forc...

Hello Chris, Thank you for prompt response. I think it is almost same point at previous talk. https://simtk.org/plugins/phpBB/viewtopicPhpbb.php?f=91&t=8469 But this time, I'd like to solve this. For example, I tried to write an example as following: SimTK::State& si = osimModel.initSystem(); osimMo...

Hello, I'm still using JointReaction in C++. In the manual, this class has setupStorage() method. I thought this would enable storage of recorded joint reaction data. But I tried to find it in OpenSim 4.0 (OpenSim 4.0-2018-08-27-ae111a49), Visual C++ did not indicate this method. https://simtk.org/a...

Hi Jessica, OpenSim is designed based on multi-body system, so each bone segment is expressed as rigid body. If you know appropriate injury criteria or threshold for femur fracture based on maximum axial, shear or bending forces, it may be good to see contact forces or joint reaction forces. If you ...

Hi, My experience with GUI would be good for positioning or scaling models. Also, marker tool is good for identify location on ground or any local frames. But if you are willing to create new body or new items, I recommend to edit osim file directly through XML editors. Modification works were back ...
