Hello,

Thank you a lot for you explanation.

Is there anyway to substitute the constraints? I'm using constraints because I can't have more than one joint in a body.

Best regards,
Marta

Hello, I've a model with 4 Constriants. When I open it in GUI it gives me this message: "Model unable to assemble: AssemblySolver::assemble() Failed: SimTK Exception thrown at Assembler.cpp:871: Method Assembler::assemble() failed because: Optimizer failed with message: SimTK Exception thrown at Int...

I tried and the same error appeared.
The directory I was using had a space in its name, I changed the name and it worked with the full path.
Now, I think it's solved.

Hello everyone, I'm trying to build a controller. I'm using xml, so from the XML browser, I took this example: <PrescribedController> <!--Flag (true or false) indicating whether or not the controller is disabled.--> <isDisabled>false</isDisabled> <!--The list of model actuators that this controller ...

Hello, I am still trying to do this. I am editing an xml model. So, with that in mind, I tried to add some contact forces. I have a model where I am trying to use Elastic Foundation Model and other one with Bushing Forces. My question now is, with these forces two bodies might be connected or is it ...

Hello again, I am still trying to do the contact between the exoskeleton and the body. I think OpenSim has 3 contact forces: Bushing Force, elastic Foundation Model and Hunt Crossley model, am I wrong? Can anyone enlighten me about which of these options it is the best? Or, what are the big differen...

Hello, I want to scale the model gait 2392. I have data for limb lenght and joint widths, however I have data for less markers than the given with the model. My ideia is to calculate a scale factor, but I don't have the measures for Gait2392. Is it available somewhere, or there is any way to obtain ...

Hello,

I am creating a model, so I have to bodies connected through a PinJoint. When I move the lower body using coordinates it separates from the upper body like if they are independent. Any ideia how to solve this?

Hi Daniel,

Thank you a lot for you explanation.

Do you think that a Bushing Force would work as a contact force?

Thank you,

Marta

Hello,

Is there any data base or something like that where is possible to find kinematic data of post-stroke gait?

Thank you,
Marta
