Member Function Documentation

DisableSelfCollisions()

void chrono::fea::ChContactSurface::DisableSelfCollisions

(

int

family

)

Disable self-collisions (default: enabled).

Calling this function results in all associated collision models being placed in the same collision family and disabling collisions within that family. Note: this function must be called before adding collision shapes to this contact surface.
