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: [fmi2logger] /var/lib/jenkins1/ws/OpenModelicaLibraryTestingWork/OpenModelicaLibraryTesting/ModelicaTest_4.0.0_ModelicaTest.MultiBody.Forces.Damper/temp_ModelicaTest_4_0_0_ModelicaTest_MultiBody_Forces_Damper_fmu/model-0qyu93ox/temp/0001_ModelicaTest_4_0_0_ModelicaTest_MultiBody_Forces_Damper (logFmi2Call): fmi2EnterInitializationMode: terminated by an assertion. error: [initialize] fmi2_import_exit_initialization_mode failed for FMU "model.root.ModelicaTest_4_0_0_ModelicaTest_MultiBody_Forces_Damper" error: [initialize] Initialization of system "model.root" failed error: [simulate] Model "model" is in wrong model state info: 1 warnings info: 4 errors
