Transient Analysis Is Not Converging for Your Model
Condition
Integrator convergence problems detected during transient analysis of this model.
Remedy
- Try slowing down the rate of profile functions used on motors or actuators in your model by changing time values or magnitudes.
- Try switching the Model Units from MKS to something else via .
- Try increasing the Output rate in the Run Motion Analysis settings so you can better see what is happening right before the error occurs.
- Enable (or disable) the controller for the motor or actuator to see whether or not it has an effect.
- Try to simplify what is happening in your model by locking motors or actuators, or using rigid groups or grounding to temporarily prevent some parts of the model from moving.
- Try changing the controller parameters (e.g. PID Gains) for the motor or actuator.
- Try starting from an equilibrium position when running transient analysis.
- Joint behavior may be too stiff, or not stiff enough. Try changing the magnitude of Motion Rates for flexible joint behavior.
- Change the Solver settings on the Run Motion Analysis window (e.g. Maximum step size, Integrator tolerance).
