Tutorial may conflict with opensim 4.5
Posted: Sun Mar 09, 2025 9:07 am
In the tutorial: Simulation-Based Design to Reduce Metabolic Cost, I found the following conflicts with opensim 4.5:
Problem 1:
After I input, an error will be reported:
Problem 2:
I followed the steps in the tutorial to compare the Total Metabolic Energy of Unassisted, Pathspring, and PathActuator, but the results do not look correct. As shown in the figure, Unassisted, Pathspring, and PathActuator are red, blue, and green, respectively.
In addition, I also directly used Scripts to print out the results of Total Metabolic Energy that comes with the model folder of opensim, and the results are the same.
Do you know where the problem is? Because this affects the implementation of the tutorial. Thank you very much.
Problem 1:
After I input
Code: Select all
pathSpring.set_GeometryPath(gastroc.getGeometryPath())Code: Select all
Traceback (most recent call last):
