Changing it to 0.005 0.005 0.005 make it look reasonable with coordinate axis of opensim. I don't know what is "coordinate axis" you said. But you can visualize dimensions in OpenSim environment using any points or markers on GUI. Also you may mind OpenSim uses "meter" as length unit. Thank you, Hide

Hopefully, following example based on MATLAB may give you some hints: osimModel = Model('model.osim'); osimState = osimModel.initSystem(); % Read IK post data Des_StoreData = Storage(IK_output_file); Des_Time = ArrayDouble(); Des_Size = Des_StoreData.getTimeColumn (Des_Time); for i = 1:num_Coordinat...

Hello, I used recent compiled OpenSim 4.0 from source (version 4.0, build date 14:29:51 Jun 6 2018). Then, I found an important issue on angular displacement with coupled coordinate. I posted similar issues on GitHub (https://github.com/opensim-org/opensim-core/issues/2208). I prepared two sample fi...

Could you check the scales around the visual object? There are two scale factors: 1) under <VisibleObject> and 2) under <DisplayGeometry>.

Hello Andrew, manager.initialize(state) state = manager.integrate(0.1) state.setTime(0) state = manager.integrate(0.1) # I believe that the manager.integrate is always based on the current state As you thinking, manager.integrate starts from current state time. Therefore, this mentioned code looks l...

Hi Chris, Thank you for your prompt responses. I see the clear of org.opensim.modeling.* cannot become any solutions for us. But it's tough to understand why MATLAB uses so much huge runtime RAM memory although any storage for force or bodykinematics were not enabled. Probably, I may think another s...

Hello, I found runtime memory of MATLAB increased so much during OpenSim simulation. When I had some simulations until 10 s of problem time, MATLAB occupied RAM more than 10 GB(!). I made clear command for all variables with relatively large arrays. But the situations have not been improved so much....

Hello Tom,

I got parent frame name as this: But I don't know why the outputs are different between "Base" and "Pin_Joint/Base_offset" setInFrames.

Thank you,

Hello Tom, Thank you for your suggestion! I appreciate your helps every time! Once I tried based on previous conversation https://simtk.org/plugins/phpBB/viewtopicPhpbb.php?f=91&t=5135 . But I realized the definitions have been changed from 3.3 to 4.0. The model was a pendulum model modified from tu...

Hello, I tried to use JointReaction with 4.0 from C++. I wrote a simple code as following: Model osimModel("PendulumJoint_type5b.osim"); SimTK::State& si = osimModel.initSystem(); JointReaction *aJointReaction = new JointReaction(); aJointReaction->setName("J_Reac_Force"); Array<std::string> jFrame(...
