Detecting and Handling Physical Clashes

You can detect and handle clashes in simulations of physical-logical models. If a clash occurs, clashing objects are highlighted, and the simulation can be stopped.

Note: If contact occurs during initialization of the model, the clash computation supposes the contact as normal; no action is performed (highlighting or stop on clash). If contact remains for the following simulation steps, no action is performed.

This task shows you how to:

Before you begin:
  1. Open a model with at least one Logical-Physical Link.
  2. Simulate the logical model.
    Note: You can also use clash handling when you replay a simulation.
Important: One of the objects involved must be fixed.

Activate Clash Computation

You can activate clash computation to compute if a clash occurs.

From the Simulation Tools window, click Activate/Deactivate Physical Clash Computation to activate the clash computation.
The clash computation is activated. If a clash occurs, objects in clash are highlighted.

To deactivate the clash computation, click again Activate/Deactivate Physical Clash Computation .

Stop on Clash

By activating stop on clash, the simulation stops when a clash occurs.

Note: If you want the exact time of the clash you must replay the simulation and check the time of the clash. (When simulating, stop is triggered by the visualization, in replay mode stop is triggered by compiler time.)

Click Activate/Deactivate Stop On Clash from the Simulation Tools window.
The simulation stops if a clash occurs.

To deactivate stop on clash, click again Activate/Deactivate Stop On Clash .
