Re: Zero Fiber Length Error in Millard2012 Muscle when running CMC with MoBL-Arms Upper Extremity Model

Just as a follow-up note, I was also able to fix the wrapping issue by scaling the surface by 20% without making it a full ellipsoid. The results were not different from one condition to the other, but the moments computed by the Muscle Analysis tool were much smaller than normal when a full ellipso...

Re: Zero Fiber Length Error in Millard2012 Muscle when running CMC with MoBL-Arms Upper Extremity Model

Hello Carmichael, Thank you for your reply! After seeing your response, I have looked deeper into the wrapping surfaces. The simulation was running into wrapping surface issues with the BIClong but not the DELT1. I'm not convinced that the issue was actually directly related to DELT1 since DELT1 nev...

Zero Fiber Length Error in Millard2012 Muscle when running CMC with MoBL-Arms Upper Extremity Model

Hello, I have been troubleshooting with an error that I keep getting when I run CMC using the MoBL-ARMS Upper Limb model (Saul et al., 2015). The error reads: Exception: Exception caught in Millard2012EquilibriumMuscle::calcMuscleDynamicsInfo from DELT1 Exception caught in Millard2012EquilibriumMusc...
