Mocap Simulation - Kinematic analysis failed

Good morning,

I’m trying to run a mocap simulation (the C3D comes from Xsens system) using the GRF predicition because we have no force plates. After several tries I didn’t find a solution: the simulation run for half a day but then a kinematic error appears (Failed to resolve kinematic constraints. Newton relaxation too small. (final kin. error = 8.009514E-001))

Anybody version is 6.0.5.4379, AMMR is 1.6.4.

I’d be very grateful for any advice/tip.
Regards
