The distance is set to s_small, although it is smaller, to avoid a division by zero when computing the direction of the line force. Possible reasons for this situation: - At initial time the distance may already be zero: Change the initial positions of the bodies connected by this element. - Hardware stops are not modeled or are modeled not stiff enough. Include stops, e.g., stiff springs, or increase the stiffness if already present. - Another error in your model may lead to unrealistically large forces and torques that would in reality destroy the stops. - The flange_b connector might be defined by a pre-defined motion, e.g., with Modelica.Mechanics.Translational.Position and the predefined flange_b.s is zero or negative. error: [initialize] fmi2_import_exit_initialization_mode failed for FMU "model.root.ModelicaTest_3_2_3_cpp_ModelicaTest_MultiBody_Forces_Damper" error: [initialize] Initialization of system "model.root" failed error: [simulate] Model "model" is in wrong model state info: 0 warnings info: 4 errors
