[solved]Fiberlength error in forward dynamics simulation using scaled model
Posted: Mon Nov 29, 2021 8:06 pm
I apologize for keeping posting.
I'm using a model based on gait2392 like the attached file.
I tried to scale the model using experimental data and perform forward dynamics simulation.
However, simulations didn't proceed not at all because of the following error in almost all muscles:
When I tried simulating using not my code but in GUI, the same error happened.
I therefore think the model muscle parameters are wrong.
Before scaling, this error hasn't been seen.
I saw this post: viewtopicPhpbb.php?f=91&t=13307&p=38202&start=0&view=
however, can scaling cause this to happen?
Is there anything I need to do?
Best regards,

Code: Select all
Error detected by Simbody method MuscleFixedWidthPennationModel::calcPennationAngularVelocity: Fiber length cannot be zero.
(Required condition 'fiberLength > 0' was not met.)I therefore think the model muscle parameters are wrong.
Before scaling, this error hasn't been seen.
