A few questions

Hello everyone

I had a few questions. Firstly when modelling gait we are meant to produce an initial “guess” in the trialsetup folder for the initial position if our model fails. Is this guess completly random or is there a process in finding the best guess. Secondly, is it possible to model gait with a THR? I have seen your AMMRV 1.5 which has a THR with somone doing a squat, would it be possible to use some of the code from this and import it into the gaitlowerextremity?

I have attached what I have done so far to this. I get an error called

[SIZE=1]ERROR(OBJ4)[/SIZE] : [SIZE=1]D:/M…s/A…s/A…1/A…1/A…n/E…s/G…y/Implants.any[/SIZE] : [SIZE=1]FemImplantNode[/SIZE] : Wrong owner class for [SIZE=1]AnyRefNode[/SIZE]. Accepted owner(s): AnyRefFrame or derived

Not sure what to do. Can anyone help please

Dear Asif,

  1. the initial guess should be as precise as possible. The model will otherwise have difficulties to start (typical error message: kinematic error in time step 0).
  2. I’m afraid it is not that simple.
    • you should use AMMR 1.5
    • you should study the structure of the THR-kneebend model to understand what is inserted for what reason
