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
Best regards
