Hello!
Now I have uploaded the model. The model was located in
Repository5.beta/ARep/Lund/…
From the start the folder was called StandingModel but I changed the name to
ElbowFlexion Model when I zipped it. Though I don’t think it makes any
difference.
I’m working with to different input data. One with loads in the hands and one
without.
//FileName = “filtElbowFlex.txt”; // with 4 kg loads in the hands
FileName = “filtNoW.txt”;// no loads
The one with loads works kinematically even when adding the driver of the GH
joint with the input data:
//FileName = “filtElbowFlexHumerus9mod.txt”;
The one without loads is the one that I sent figures of. Now I made a little
change in the Mannequin file, because I found there the following line:
AnyFolder Load = {
AnyVec3 TopVertebra = {0.000, 0.000, 0.000};
AnyFolder Right = {
AnyVec3 Shoulder = {0.000, 0.000, 0.000};
AnyVec3 Elbow = {0.000, 0.000, 0.000};
AnyVec3 Hand = {0.000, 0.000, 150.000}; ???
So I wander why is there a load in the hand but no loads anywhere else. I
changed it to 0 load in the hand. But then the Dynamic Analysis didn’t give the
same result as before and a few seconds before the end it stopped.
Well, if you have time to look at it, please do. I thÃnk I need also some help
to add the weight to the hands as you recommended. I’m not sure in what file I
should make the changes.
Also I must say that the RMS data that I showed you might be wrong in time a
hole second. So from the matlab figure I sent you cannot compare it to the
AnyBody Result.
Best Regards,

Hi Signe
I have taken a look at the graphs and the explanation, it looks at
bit strange that the acitivity from the model is out of phase with
the inclination. One reason could be acceleration forces, have you
checked the values of the segments in the arms? You may find them
in the model tree under segments as rDDot.
The activity from a model can be compared with EMG although the
height of the curves can not be compared directly. There is also a
phase shift because the muscles EMG will occur slightly before they
develop the force and activity.
If you continue to have problems please zip your model and upload it
and we will have a look at it.
Best regards

inclination results has been devided with pi, and the RMS results
with the maximal measured activity during this measure, to be able
to put all results in the same figure.
