I have a problem with my stationary Bike model?

hi
I modeled a stationary bike to study about forces exerted to knee and mudcles, my model had a correct result kinematicly, but in inverse dynamic study lead to this errore:
[SIZE=1]ERROR(OBJ.MCH.MUS4)[/SIZE] : [SIZE=1]C:/U…s/s…f/A…a/R…g/A…y/A…x/A…0/A…n/E…s/p…i/PedalDemo.Main.any[/SIZE] : [SIZE=1]Study.InverseDynamics[/SIZE] : Muscle recruitment solver : solver aborted due to singular KKT matrix

how can i resolve it, please?
thanks

Hi,

This error message typically indicates that some degrees of freedom are not carried.

Why dont you have a look at the Example BikeModel3D and compare what’s done there. Or even easier use that example and configure your settings in that model.
