I loaded the plugin, opened the model, and attempted to run a 0.1-second simulation, but the integrator did not seem to be progressing. Please provide instructions for how to reproduce the issue. I suspect there may be an issue in the plugin, which cannot be diagnosed without looking at the code. T...

I loaded the model you provided in your first post but received "Object type Millard12EqMuscleWithAfferents not recognized" errors so I was unable to reproduce the issue to investigate. However, I loaded the arm26 model that accompanies the 4.0 installation and confirmed that no active muscle force...

Gravity and/or passive muscle forces?

Gravity was setted to 0.

Here's passive forces.

Dear all, I'm using an upper limb .osim model with 6 millard muscles and 2 DoF. I'm using a modified version of the MoBL upper limb model with only the following muscles: DELT3, PECM1, TRIlong, TRIlat, BICshort, BRA. Muscle parameters are taken from the original paper of the model: https://www.ncbi....

Dear all! I set up a Forward Dynamics Simulation in Simulink with these settings: - solver = RungeKuttaMerson Integrator (ode4) - fixed step value = 0.01 I forced OpenSim to use same step size and make it constant with an integrator accuracy of 0.1. Now my simulation results have a fixed number of s...

Ok, I set up Simulink step to a fixed value (0.01) and I forced OpenSim to use same step size and make it constant with an integrator accuracy of 0.1. Now my simulation results have a fixed number of steps and it takes less time. I have another question. When I perform some test on that model, I not...

Yes, I'm using a modified version of the MoBL upper limb model with only the following muscles: DELT3 PECM1 TRIlong TRIlat BICshort BRA Muscle parameters are taken from the original paper of the model: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4282829/ The unique parameter I changed is the contra...

Dear all, I'm using this interface to create a forward simulation in Simulink for setting muscle excitations and retrieving some output information. https://simtk.org/projects/opensimmatlab I used an upper limb .osim model with 6 millard muscles and 2 DoF. I setup a Manager object with Runge-Kutta I...

I got this error with MATLAB R2018 version but I solved it with R2017 version.

UPDATE: Ok, It works now!

The problem was in the socket tag on xml code in the .osim model file.
