visualization of muscle forces

Hi,

(hope i don’t ask too many questions)

is it somehow possible to visualize the resultant force vector of all muscle forces acting on a certain segment?

Thanks,

Thomaz

Hi Thomaz,

I don’t think there is something easy by default in the AMS to visualize those forces. If you add them up in a vector individually, you could create one resultant Force Vector and visualize that, but I don’t think that’s what you want.

Thanks Amir!

At least this would be a solution, Is there an example how to create a vector and how to visualize it?

Regards,

Drawing a Vector:
look under AnyDrawVec in the reference Manual for the description and an example, it should look at the end like this:

AnyVec3 ForceVector = ReactionForce;

AnyDrawVector DrawForce = {
Vec = .ForceVector ;
GlobalCoord = Off;
AnyRefNode &SphereI = Main.Node1;
Line.Thickness=0.0025;
Line.RGB={0,1,1};
Line.End.Style = {5} ;
Line.End.Thickness = 3Line.Thickness;
Line.End.Length = 4
Line.Thickness;
Line.Start.Style = {0};
Line.Start.Thickness = 3Line.Thickness;
Line.Start.Length = 3
Line.Thickness;
Line.Start.RGB = {1,0,0};
};

Creating a vector:
this should be done with a AnyVec3:
AnyVec3 <ObjectName> = {0, 0, 0};

this algebraic vector has a “x, y and z” component, and you have to get that component from the Force. You can than add, subtract, multiply, transverse or normalize those vectors as any other algebraic vector.
