muscle force changed after reading in a text file

Archive AnyScript Yahoo archive

Hello,

I read in a text file to draw a vector dependent on the time.
After that I checked the muscle forces again and I don’t know why, they
changed. How is this possible?
Thanks.

Hi Silren

That sounds very wired… are you sure nothing changed? Could you
check when the files was edited last, to be sure nothing changed?

Maybe I should tell exactly what I did:

AnyForce3D ReadEMinimusOne = {

AnyFunInterpol force = {
Type = PicewiceLinear;
Filename = “EMinimusOne.txt”
};
AnySeg &ref = Main…;
F = force(t);
};

and then I drew the vector with the AnyDrawVector function.
The strange thing is that the higher the values in the textfile the
higher the muscle forces after the inverse dynamic analysis.
Is there a correlation?
Then I also have another question, how can I draw a node time
dependent when I have the position x,y,z from the output?

Kind regards,
Silke

Hi Silke

Sorry about the slow repond on this message…

The reason why your muscles forces are going up after you applied
your drawvector is that you are also applied a force.

You are creating your AnyFunInterpol object inside a AnyForce
object, and you are applying the interpolated force to a segment by
writing “AnySeg &ref =Main”, so unless your vector is zero you are
applying a force to the model.

If you would like to create a drawvector without applying any force
you should just write something like this …

AnyFunInterpol force = {
Type = PicewiceLinear;
Filename = “EMinimusOne.txt”
};

AnyDrawVector vector={
vec =force(t);
…

};
