⃰Friction coefficient values for contacts are ignored in the Explore stage, but separation is allowed.
⁑ Stiffness behavior for remote displacements is handled differently in Explore and Refine modes. In the Explore stage, Discovery uses a rigid behavior. However, Discovery uses a flexible behavior in the Refine stage.
⁂ The Refine stage always uses a displacement condition. The Explore stage uses a displacement condition if the face is aligned with the global coordinate system but uses a rigid joint otherwise.
✣ The Explore stage uses a rigid formulation of the joint, while the Refine stage uses a deformable formulation of the joint.
✱ The Refine stage always uses a frictionless support, while the Explore stage uses a frictionless support if the face is planar and a rigid joint otherwise.
