About Vertical Clearance

Checks for impacts both above and below the vehicle.

This drive mode allows you to model the vertical movement envelope of a vehicle, which enables you to check for grounding of the vehicle or overhead impacts with other structures. The vehicle is assumed to have all wheels in contact with the road at all times. In the case of multiple axles this means that there may be some vertical movement of individual axles. This movement approximates to the behaviour of the vehicle's suspension.
