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.

Re: SimTK Initial Velocity Analysis:
Sadly, no. There is a nice Assembly analysis in Simbody but no InitialVelocity analysis (there should be!)
You can work around that by adding a velocity constraint (or Motion object) to one of the dofs (assuming a net-1-dof system). Then constraint projection will figure out all the other velocities.
See System::projectU() and related functions.

Great! Thanks Sherm. I'll look into that. I appreciate your help.
