Main Forum

Hi,
I am a beginner to anybody. I was just trying to apply vertical load to hand of 5 kg with different positions of hand like glenohumeral abduction at 90 degree ? My mannequin doesn't have anyfolder loads options in it N when I tried writing into it there is no change in output with load being applied and load being not applied.
2nd questions is
So by changing the values of glenohumeral abduction in the mannequin folder changes the position of body in simulations also?

Hi

Welcome to the forum,

Which model are you using?

How did you apply the loads? this can be done using e.g. AnyForce3D please note the force needs to included into the AnyBodyStudy to have an effect.

Depending on which model you are using it may change the abduction the FreePostureModel will do that.

Best regards

ohh okay I understood. I have to include AnyForce3D command into AnyBodyStudy folder. But When I did that it is showing error as HumanModel objected unresolved.

Hi

The unresolved object error you will get if the name for the human model is not correct.

Try to locate the node you would like to add the force into in the ModelTree first then right click and copy complete path, then paste it in as the name.

So eg.
Main.HumanModel.BodyModel.Right.ShoulderArm.Seg.Hand.Ref.PalmJoint

Hi,
Thanks a lot . I got the required result. Just one more question why in this case AnyForce3D should be added in AnyBodyStudy folder to take effect? Because when I see another AMMR examples there is no such thing which is present inside that folder. Thanks in advance

Hi

It is the same for all models the objects needs to be inside the study one way or the other.

There are several ways an object can be part of the study examples;


AnyBodyStudy  MyStudy ={

AnyForce3D myforce ={…..}

};

or

AnyForce3D myforce ={…..};

AnyBodyStudy  MyStudy ={

AnForce3D &ref=.myforce;

};

or

AnyBodyStudy  MyStudy ={

#include "MyForceDefinitionInAFile.any"   //this is a file containing  AnyForce3D myforce ={…..};

};

So in many models the studies includes multiple files, which contains the objects, but the models will be the same in all the three cases displayed here it will have the force object inside the MyStudy.
