Static Optimization Constraint Fail
Hello! I am trying to run the static optimization tool using OpenSim 4.0. I am also using an extra file to append actuators to the model but am still getting this error below: SimTK Exception thrown at interiorpointoptimizer.cpp:264: Optimizer failed: Ipopt: Infeasible problem detected (status 2) OP...

Re: Error loading mesh file
Yes it loads correctly in the GUI. Would trying OpenSim 4.0 potentially fix the bug? I will look at the link you sent me as well.

Re: Error loading mesh file
What if I have the file in the main folder that the model is in and the geometry folder?
Also this is a contact geometry file so the code reads:
<filename>scapula.obj</filename>

Error loading mesh file
Hello, I am trying to run the static optimization tool and when I load my motion file and start to run I get this error: Exception: Error loading mesh file: scapula.obj. The file should exist in same folder with model. Loading is aborted. This scapula file is in the exact same folder that my model i...

The ligament is defined as:

Interpolating ligament curve during forward dynamics
Hi, So I've created a very simple model to better understand how the ligaments will run before I implement them into my more complicated shoulder model. My current model has a sphere of radius .5 with a mass of 2 dropping with the resting length of the ligament being .5 and the psca_force being 40 (...

Re: Updating Muscles in Model
Hello! I have not tried updating the model I am working on from Shutte1993Muscle_Deprecated muscles yet, but according to a webinar found here: https://www.youtube.com/watch?v=Q1rId1fOkjw I believe it is as simple as typing in the name of the type of muscle you want in for the old one. Generally the...

Applying an external force
Hello! I am working with an upper extremity model, and I want to apply a force that will constantly be applied at the center of the hand for a forward dynamic simulation. Without using motion capture systems and force plates to generate a motion or storage file that can be applied to the forward dyn...
