I am really new to anybody modelling system, and now I have encountered a problem on AnyMechOutputFileForceExport class result.
This is the procedure that I have done and the problem is mentioned at the end (4):
-
I have loaded standing model of repository
-
then added the mentioned class in this way in my study:
AnyMechOutputFileForceExport FEAOutPut =
{
FileName = “FEAOutPut.txt”;
AnySeg &Pelvis = Main.HumanModel.BodyModel.Trunk.SegmentsLumbar.PelvisSeg;
}; -
then run the inverse dynamics
-
got the FEAOutPut.txt as an output
-
encountered these problems:
4.1. What is the meaning of F[3] or F[i] in which i>2? (anybody tutorial says F[0]=Fx, F[1]=Fy, F[2]=Fz)
4.2. What is the meaning of M[3] or M[i] in which i>2? (anybody tutorial says M[0]=Mx, M[1]=My, M[2]=Mz)
4.3. I have imported the output file to MS Excel and added the forces in each row and summed them up but the results were:
ΣFx = -4.64E+02 (?)
ΣFy = 5.84E+02 (?) (maybe because of pelvis segment weight but not this much)
ΣFz = -1.56E+01 (?)
which were not zero in x and z directions and equal to the segment weight in y direction.
would any body please tell me why this is happening and how can i fix this issue?
In advanced I have attached the Output file “FEAOutPut.txt”, Excel file which I have made “FEAOutPut.xls” and the code in which I have inserted the class in zip file.
