Scaled body parts

For the partial body models in the AnyBody 1.3.0 Repository (Spine Two
Legs, Spine Two Arms, etc), is the BodyMass in the main file the total
body mass of the individual and scaled within the software to reflect
the parts of the body we are looking at? Or should the BodyMass in
the Main file reflect the mass of the body segments we are looking at
based on our own calculations from Winter, for example? So, for
example, if I am looking solely at an arm, should I put the BodyMass
to be the mass of the entire individual such as 70kg, or should I
determine the BodyMass be strictly the mass of the arm, say 8kg (or
whatever that value would be based on anthropometrics)?

Thank you for your help.

Hi Sarah

In the Repository 5 i assume that this is the repository you are using, the mass
should in general not be present in the main file, it still are though for some
models using the Leg2D model (Bike2d and BikeSpring). I searched the
applications and found it to be present also in the GearStick problem, in this
problem however it is not used anymore and could be removed.

The correct way to specify the mass is to use an AnyFamily file. A good place
to start, is to look at how this is done in the the StadingModel.main.any file.

In this file you will find the following lines:

//Pick one of the scaling laws

//Do not scale

// #include “…\BRep\Aalborg\Scaling\ScalingStandard.any”

//Scaling unifromly in all directions to macth segments lengths

//#include “…\BRep\Aalborg\Scaling\ScalingUniform.any”

//Scaling taking length and mass of the segments into account

//#include “…\BRep\Aalborg\Scaling\ScalingLengthMass.any”

//Scaling taking length, mass and fat of the segments into account

#include “…\BRep\Aalborg\Scaling\ScalingLengthMassFat.any”

Scaling={

#include “…\BRep\Aalborg\Scaling\AnyFamily\AnyAnne.any”

};

So in this model a scaling law taking heigth weigth and fat percentage was used
together with the file AnyAnne.any which is where the segments lengths and their
masses are specified. You may created your own file like AnyAnne.any to reflect
the size of the person you want to model. See also the file AnyJack.any which
calculates masses based on total mass, according to winters rules.

I hope this answers your questions otherwise please do not hesitate to ask again

Thanks for getting back to me. I am actually using repository 4. I
assumed that 5 was for version 2.0, was that incorrect? Is 5 compatible
with AnyBody version 1.3.1? I believe that we have a contract to
continually get updated software versions, and we haven’t gotten 2.0 yet
(is there a process that I have to begin to get the ball rolling on it?).
So I have been using repository 4.

How does repository 4 go about scaling?

Thanks for your time,
Sarah

Hi Sarah

The repository 4 can not scale the models, and you are right that
repository 5 will only run on the newest preview version. This is
because this repository make use of scaling functions which are new
in the preview version.

You may download the Preview (beta) version of AnyBody from
www.anybodytech.com
if you log into the members area with your user name and password

Best regards
