Hey Leigh,
I just ran your model and found some wrong settings. It might be simple to get the C3D project running.
First, have a look at your LASI and RASI markers. I think they are switched.
Second, try not to optomize all the bone segments. Switch all of them off, see if it runs, then turn them on one-by-one. I guess pelvis optimisation might cause trouble in your case. Additionally, some users have trouble with the thigh optimization.
I switched LASI and RASI and changed it to no pelvis width optimization and it made 151 steps kinematically immediately…
Details:
Change 1 in the markers.any
CreateMarkerTDWidget LASI ( //this was RASI before
MarkerName=PrefixDef(LASI), //this was RASI before
MarkerPlacement=Trunk.SegmentsLumbar.PelvisSeg,
OptX=“Off”,OptY=“Off”,OptZ=“Off”,
WeightX=1.0,WeightY=1.0,WeightZ=1.0,
Model1=MotionAndParameterOptimizationModel, Model2= InverseDynamicModel
) = { sRelOpt = {0.11, -0.03, 0.145}};
CreateMarkerTDWidget RASI ( //this was LASI before
MarkerName=PrefixDef(RASI) , //this was LASI before
MarkerPlacement=Trunk.SegmentsLumbar.PelvisSeg,
OptX=“Off”,OptY=“Off”,OptZ=“Off”,
WeightX=1.0,WeightY=1.0,WeightZ=1.0,
Model1=MotionAndParameterOptimizationModel, Model2= InverseDynamicModel
) = { sRelOpt = {0.11, -0.05+0.02, -0.145};};
Change 2 in ModelSetup.any
