RE: About ControlLinearNode

<t>Thank you, Ayman.<br/> I misunderstood the usage of this class.<br/> <br/> My purpose is to create a series of control nodes, and let the algorithm to search for a new sets of nodes which could minimize the value of objective function.<br/> <br/> I have to look for other ways to implement codes w...

About ControlLinearNode

<t>Hi all<br/> <br/> What are the differences of these two constructor under ControlLinearNode class?<br/> <br/> 1.ControlLinearNode (double aT=0.0, double aValue=0.0)<br/> 2.ControlLinearNode (const ControlLinearNode &aNode)<br/> <br/> I've tried both of them. For the first one, I splitted the ...

Model Validation

<t>Hi all<br/> <br/> I'm curious about the validation of OpenSim musculoskeletal models.<br/> <br/> Is it necessary to acquire subjects' joint moment data with dynamometer? <br/> <br/> or alternatively, after <br/> 1.the segmental parameters being scaled, <br/> 2.residuals reduced, <br/> 3.the reser...

RE: prescribed dof in forward dynamics

Thank you, Ayman. It works.
I copied the cubic spline function used in .osim,
and pasted experimental values as <y> values.
It works!
I really appreciate your help.

RE: prescribed dof in forward dynamics

<t>Hi Ayman<br/> <br/> Would you please show me how to specify the <prescribed_function> in .osim file?<br/> <br/> I tried to input something like:<br/> <prescribed_function>q= 15.526*t^2 + 2.8708*t - 0.2104</prescribed_function><br/> <br/> But it didn't work. Besides this, is there any tag that sho...
