Access a certain value at the specific moment of the analysis during param study

Hi,

I could receive the index of the minimum value of a joint moment while a certain motion is analyzed from motion data. And this is used for parameter study.



AnyParamStudy ParamStudy = {
  Analysis = { ... };
  AnyDesVar Var = { ... };

  AnyDesMeasure Min_JntM = {
    Val = min (..Study.JntM());   
  };
  AnyDesMeasure Index_Min_JntM = {
    Val = argmin (..Study.JntM());    // the moment when JntM is the minimum
  };
};

However, I’d like to receive another analysis value, i.e., the joint angle, at Index_Min_JntM (when JntM is minimum).
And I also want to save this angle value at the moment (of minimum JntM) as an AnyDesMeasure class.

I tried to make an AnyOutputFun class of the joint angle. But I did not find the way to access the specific joint angle value at the specific moment (with Index_Min_JntM) .
How can I access the value of the joint angle with the certain index number, and output it with AnyDesMeasure?


  AnyDesMeasure JntAngle = {
    Val = ....??? ;
};

Thank you.

Hi Dong-Pyoung,

It will be better if you can create a simple example which contains your concepts based on our Demo Arm 2D model.

If you can upload that then we may be able to figure out how to improve that.

I attach a script file for an example.
Thank you. :slight_smile:

Hi Dong-Pyoung,

Sorry for late reply.

Dear Moonki,
I still feel awkward to access certain data structures of AnyBody sometimes.
Thank you very much!
