Hi OSIM-Team
During running a Static Optimization the following warnings show up:
time = 7.42 Performance =367.867 Constraint violation = 2.7079e-005
WARNING: No suitable initial conditions found for

WARNING: Millard2012AccelerationMuscle::computeInitialFiberEquilibrium(SimTK::State& s)
Continuing with an initial fiber force, length and velocity of 0, 0.177001 and 0
Here is a report from the routine:
Solution Error : 1.148576 > tol (0.000006)
Newton Iterations : 500 of max. iterations (500)
Check that the initial activation is valid, and that the whole
length doesn't produce a pennation angle of 90 degrees, nor a fiber
length less than 0:
Activation : 0.000000
Whole muscle length : 1.#QNAN0
I don't understand what exactly this means?
Best, Sandy
