Hi Bryce, Here is a code snippet for an ellipsoid wrapping object ellipsoid = osim_model.getBodySet().get(0).getWrapObjectSet().get(4) wrap_ellip = osim.WrapEllipsoid.safeDownCast(ellipsoid) initial_dim = wrap_ellip.getRadii() # value: [0.1,0.135,0.08] wrap_ellip.set_dimensions(osim.Vec3(0.1, 0.235,...

Hi Bryce, I am not sure what changes were included in the 4.1 version, but I had a compiled version from the gihub repo somewhere between the 4.0 and 4.1 Opensim releases. I was able then to modify the properties of the wrapping objects via pyhton by safe downcasting the functions from the class cor...

Hi, I think while the activation was overridden to 0, Opensim relies on the default values (min activation) of the muscle to plot the active fibre force. I am not sure if you are using a Thelen muscle but as you can see here : https://github.com/opensim-org/opensim-core/blob/9d6e9b1e2f0aaf43622cffe8...

Hi,

If you are connecting your body to the ground, you can find an implementation in python here: https://github.com/pyomeca/pyosim/blob/ ... le.py#L205

Hope it helps.

Hi, The wrapping objects are created under their frame. In the GUI, you can find the information in the model tree in the navigator. Under each body, you can see the wrapping objects (INFSPcyl) fixed to its frame (scapula). Tree_wrap.PNG In the osim, it is the same logic, under each body of the body...

Hi,

I had a similar issue, except I work with python, so I am not sure the solution would be the same.
In my case, I had to update the model's ForceSet, instead of the muscle set, to be able to successfully save it in the new osim file.

Hope it helps,

Hi,

Using the EMG data, there is the CEINMS toolbox (https://simtk.org/projects/ceinms) that calibrates musculo-tendon parameters including the muscle max isometric force.

Hope it helps,

Hi, I see you are using python. So, you can start by adding the storage file info such as the column or row number using new_table.addTableMetaDataString() supposing new_table is the TimeSeriesTable you created. Then, you can save it as a storage file output_file using: adapter = osim.STOFileAdapter...

Hi,

If you open your IK xml file, you can change <report_marker_locations> to true. After you run the IK tool, and additional file is created with the location of your markers in the Ground.

Hi, Using the projection method improves your chances of having a flat foot at the end of the scaling, supposing it is in contact with the ground. Thus you can only use this approach correctly for the Z direction. Supposing you have no additional data, you could try to use the average of Heel-Medial...
