UpperLower Body Model

[Nate Roiger]

Has anyone ported the UpperLower Body Model (https://simtk.org/projects/ulb_project) to OpenSim 4.3?

I'm getting an import error saying it should be saved with 3.3; but I can't find the 3.3 release anywhere. If anyone has 3.3 installed, could you try to update it?

Code: Select all

Model file C:\Users\Tweak\Documents\OpenSim\4.3\Models\ULB_Project\UpperLowerBody.osim is using unsupported file format. Please open model and save it in OpenSim version 3.3 to upgrade.
	Thrown at Model.cpp:109 in Model().

Previous versions of OpenSim can be found on the download page: https://simtk.org/frs/?group_id=91

Click the "Previous Releases" dropdown under the first section to see them all.

Thanks - not sure how I missed that download section. With 3.3 installed I can convert the current UpperLower Body Model; but 4.3 complains when importing. I've attached the updated model

The following Warnings/Errors were encountered while loading the model:

Model 'UpperLowerBodySimpleModel' has inconsistencies:
Coordinate 'deviation' was labeled as 'Rotational' but was found to be 'Coupled' based on the joint definition.
Coordinate 'flexion' was labeled as 'Rotational' but was found to be 'Coupled' based on the joint definition.
Coordinate 'deviation_l' was labeled as 'Rotational' but was found to be 'Coupled' based on the joint definition.
Coordinate 'flexion_l' was labeled as 'Rotational' but was found to be 'Coupled' based on the joint definition.
You must update any motion files you generated in versions prior to 4.0. You can:
  (1) Run the updatePre40KinematicsFilesFor40MotionType() utility (in the scripting shell) OR
  (2) Re-run the Inverse Kinematics Tool with the updated model in 4.0.
In versions prior to 4.0, we allowed some Coupled coordinates to be incorrectly
labeled as Rotational. This leads to incorrect motion when playing back a pre-4.0
motion file (.mot or .sto in degrees) and incorrect inverse dynamics and
static optimization results.

For (1) I'm getting python import errors when importing opensim

Code: Select all

>>> import opensim
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "D:\OpenSim 4.3\sdk\Python\opensim\__init__.py", line 6, in <module>
    from .simbody import *
  File "D:\OpenSim 4.3\sdk\Python\opensim\simbody.py", line 13, in <module>
    from . import _simbody
ImportError: DLL load failed while importing _simbody: The specified module could not be found.

And for (2) I dont see how the Inverse Kinematics Tool applies - the model has no markers. Is that OK? What IK Tool Settings XML file should be used.

I am facing the same issue
