parameter difference 2392 model and scaled model

[Chitra M Das]

I compared 4 parameters between OpenSim model 2392 and scaled model: maximum isometric force, optimal fiber length, pennation angle and maximum contraction velocity. but there was a slight difference in the optimal fiber length between the two models, while the other 3 parameters showed same values for both the models.

Have I gone wrong with scaling or is there any other reason behind it?

When scaling a model, only the optimal fiber length gets scaled since it is unknown what the other how the other parameters map to the size of the subject. It is up to you to alter the remaining parameters for your subject.
