Re: Importing bodies from existing models in OpenSim3.3
Hi Ayman, Thank you for your response! To clarify I have OpenSim 3.3 installed currently and the base model I am using is from a SCONE example which I believe is also using 3.3. Having learnt the MATLAB API for OpenSim 4.1 I was using it as a reference for rebuilding the code in an earlier version. ...

Re: Closed kinematic loops
Hi Thomas, Thank you for your response and sorry for the delay in reply. I did create the model using OpenSim 4, do you know when SCONE might start supporting it? Since seeing your response I have been trying to build the equivalent model in OpenSim 3.3 but have had difficulty (I have been posting i...

Importing bodies from existing models in OpenSim3.3
Hi All, I am currently trying to convert a file backwards from 4.2 to 3.3 for use in SCONE. I have taken a pre existing gait model and loaded it into MATLAB. In 4.2 I used the following command to load the bodies in as variables so that I could make additions to them. % BodyList = osimList2MatlabCel...

Closed kinematic loops
Hi All, My project involves looking at how exoskeletons and the body interact. As part of this, I have produced a closed kinematic loop with the two chains connected by a point constraint at the ankle joint. The model has built on the SCONE example 4a lower limb model and I was hoping that I would b...

Re: Closed Kinematic Chains
Hi Ayman, Thank you for your response. You are correct the issue was due to the structure of the multibody tree, to form the closed kinematic chain I needed to use a constraint rather than a joint for the final connection between the exoskeleton and body. Ended up using the PointConstraint() for any...

Closed Kinematic Chains
Hi All, I am using the 2D MOCO example to test a model I would like to run. Building on the 2D_gait.osim model I have added a single DOF exoskeleton on either side matching the joints of the skeleton model using pin joints (hip, knee and ankle). The hip section attaches at the pelvis with a weld joi...

Hi Ross,
Cheers for the response. I'll have another comb through the OpenSim forum then post it in there!
Best wishes,
Rory

Parallel chain linking for
Hi All, I am building on the 2D MOCO example to test a model I would like to run. Building on the 2D_gait.osim model I have added a single DOF exoskeleton shell on either side matching the joints of the skeleton model using pin joints. The hip section attaches at the pelvis with a weld joint, the sy...

Re: Smooth Sphere Half Space Force Parameters
Hi Nick,
Great! I had tried a couple of variations but not that one!
Thank you very much for your help,
Rory

Smooth Sphere Half Space Force Parameters
Hi All, I have recently started using MOCO having worked with OpenSim for a while. It is fairly well documented within this Forum and in a few papers, that the HuntCrossleyForce model needs to be changed to a SmoothSphereHalfSpaceForce. Having looked at the .cpp definitions for both (https://simbody...
