SimTK Initial Velocity Analysis:
Is there a SimTK function to do initial velocity analysis for a closed-loop system? Something similar to sdinitvel function of good old SDFAST?
Thanks.
Musa
Thanks.

Re: Using SimTK Assemblar object to assemble Closed-Chain systems
Thanks a lot Sherm. That works for compilation. Now I have another problem. The assembler only runs once: assembler.getNumAssemblySteps() = 1 and assembler.getNumGoalEvals() = 1. The gen coords are not changed from their mis-assembled values. Am I doing something wrong or missing a step somewhere? T...

Using SimTK Assemblar object to assemble Closed-Chain systems
We are trying to enforce constraints for a system with closed-chains using the Assembler object using the following: auto &system = osimModel.getMultibodySystem(); Assembler assembler(system); assembler.assemble(state); This assembles the model but most of the generalized coordinate bounds were viol...

Re: MocoOutputTracking Goal Problems:
Great. Thanks Nick. We do use the setOutputIndex() function to select the desired index of the vector to use for the foot position. We appreciate your insight and look forward to a future version that allows inclusion of dynamic stretching of the reference desired trajectory to match the current tim...

MocoOutputTracking Goal Problems:
Hi, We have two questions that we hope someone can help us with: Q.1. We want to track the trajectory of a particular body segment (such as the toes) with MocoOutputTrackingGoal. We defined the output path for the body as: "FootGoal->setOutputPath("/bodyset/ltoes|position");". Is this the correct wa...

Controller Plugin crashes OpenSim
I have a problem that started since OpenSim 4.2 and up to the current 4.4. I defined a muscle controller function and created a dll file as a plugin for it. In these versions of OpenSim, the GUI will only load the model files containing this controller if I add the file to a 'plugin' folder and put ...

Building C++ code in Windows Visual Studio with OpenSim static libraries
Has anyone succeeded in building a Windows Visual Studio API application (C++) with OpenSim static libraries only? I have tried this in several ways with no success. I will appreciate any insight on how to do this if at all it is possible.

Re: Plugin Error:
Thank you very much for that guidance. It works; after I have cleaned out my previous API installation and made a fresh installation with a more recent version. Apparently I must have been mixing versions of the API and GUI installations. Thank you.
