How exactly do I define the pelvis as being in contact with an external support (which isn’t modelled), as the subject is seated on a bicycle seat with the legs not touching the ground, and the subject is moving their legs with the seat fixed to the ground.
I want AnyBody to predict the reaction forces at the pelvis but have no idea how to do this. I listened to this webcast: ‘Modeling Human-Exoskeleton Interaction With AnyBody’ and the presenter was talking about ‘AnyReact’ forces (couldn’t hear him clearly enough) and was saying that you could constrain muscles to be fixed in order to calculate reaction forces – but he didn’t explain how this is done in AnyBody.
the code you are free to place anywhere in the model as long as the folder you add it into is part of the study you are using.
A good place would be eg. Main.Model.ModelEnvironmentConnection folder you can find this in the main file.
The pelvis segment can be found in
One way to find such a location would be to double click the pelvis in the modelview this will take you to the modeltree where the drawing object for the pelvis has been created inside the pelvis segment.
I get an error that ref1 object is already declared:
ERROR(SCR.PRS1) : C:/U…s/j…1/A…a/R…g/A…y/D…s/A…o/A…n/M…s/M…e/FreePostureFullBodyStatic.Main.any(87) : ‘ref1’ : Object already declared at :

Model loading skipped
However when I made all the four instances of ref different numbers such as ref1, ref2, ref3, ref4 I get an error:
ERROR(SCR.PRS17) : C:/U…s/j…1/A…a/R…g/A…y/D…s/A…o/A…n/M…s/M…e/FreePostureFullBodyStatic.Main.any(86) : ‘ref1’ : Reference of class AnyRefNode cannot refer to an object of class AnyFixedRefFrame

How do I fix this? And then where do I go from here?
