LINK_BEAD


ID_NAME	= `<id_name_of_link_bead>`	Name of `LINK_BEAD` definition.
CS	= `<name_of_coord_system>`	Name of the coordinate system in which the link condition is defined. Only Cartesian coordinate systems are allowed.
TYPE		Type of link condition
	= `PLANE_SYM`	A symmetrical displacement of the nodes referring to the plane that lies normal to the given axis of the coordinate system.
	= `POINT_SYM`	A symmetrical displacement of the nodes referring to the origin of the coordinate system is enforced.
	= `ROTATIONAL_SYM, AXIS_1` = `ROTATIONAL_SYM, AXIS_2` = `ROTATIONAL_SYM, AXIS_3`	A rotational symmetric displacement of the nodes referring to the given axis of the coordinate system is enforced.
CLIENT_DIR	= `<X_1>`, `<X_2>`, `<X_3>`	Normal direction of the symmetry plane for `PLANE_SYM` with reference to the specified coordinate system for sensitivity-based bead optimization.

Remarks

When using LINK_BEAD, the geometry of the model must be symmetric. However, the underlying mesh might be asymmetric.
For bead sensitivity, only LINK_BEAD with TYPE = PLANE_SYM is allowed, while all other TYPEs are only allowed for bead controller.
