DFBI Field Function Reference

Obtains the minimum distance between each face of the body surface and the nearest face on the opposing boundary, for the last iteration. If sub-stepping is used, the minimum distance is the global minimum of all sub-steps of the last iteration. The minimum distance is projected onto the boundary normal. There is one Minimum Contact Distance available for each contact coupling in the simulation, so that results can be evaluated for each coupling separately. For body-body couplings, the Minimum Contact Distance is only available for the first of the two bodies.

To access this field function, select the Solvers > 6-DOF Solver node and activate Temporary Storage Retained. Perform at least one iteration to populate the field. When you close the simulation and then restore it, the Minimum Distance field does not contain any values. You must perform at least one iteration to populate it again.

Automatically computes the initial relative velocity for the bodies that participate in the constraint with index 1. The computation is based on the initial velocity and angular velocity of these 6-DOF bodies and the direction defined by the driver constraint.

The velocity specified in a velocity driver constraint must be consistent with the initial velocity and angular velocity of the 6-DOF bodies. The same holds for the time derivative of the distance specification of a distance driver constraint.
