GROUP_AUTO


ND_GROUP	= `<name_of_node_group>`	Name of the parent node group.
CS	= `<name_of_coord_system>`	Name of the coordinate system.
TOL	= `<tol_1>`, `<tol_2>`, `<tol_3>`	Tolerance values in the coordinate directions of the referenced coordinate system.
SEARCH _TYPE		Search criterion.
	= `CONTINUOUS`	Continuous search.
	= `DISCRETE`	Discrete search.
	= `CS_MULTI`	Search for nodes with the same coordinate values in the specified coordinate systems.
SEARCH_DIR	= `<cs_dir>`	Search direction.
	= +1 = -1 = +2 = -2 = +3 = -3	positive (+) or negative (-) direction of 1st, 2nd or 3rd axis of coordinate system `CS`.
SEARCH_LEN	= `<value>`	Search length.
DISCRETE_LEN	= `<value>`	Discrete length.
SEARCH_CS	= `<name_of_search_cs>`	Name of the search coordinate system.

Remarks

The command is applied only to nodes that have been selected. The child node group only contains the necessary parent nodes for the case the parent nodes are also selected.
The command GROUP_AUTO_DEF does not have its own ID_NAME.
ND_GROUP is compulsory. The name of the parent node group with an attached '_' plus a numbered index is used for all child node groups. Should the name end with the symbol '_', no other symbol '_' is attached.
CS is compulsory.
TOL is compulsory. The tolerance values must be positive. At least one of the three tolerance values must be accepted. For tolerance values not accepted, the smallest of the given tolerance values is acceptable. The three tolerance values are coordinate values that refer to the three coordinate directions of the CS. In a Cartesian coordinate system all three values have the longitudes <tol_*>. In a cylindrical coordinate system <tol_1> and <tol_3> are longitudes and <tol_2> is an angle measured in degrees. In a spherical coordinate system <tol_1> is a longitude and <tol_2> and <tol_3> are angles measured in degrees. Tolerance values should be big enough to include the individual nodes and small enough not to include the neighboring nodes not wanted.
SEARCH_TYPE is compulsory. The relevant criteria is that of Version 3.0.
SEARCH_DIR is compulsory for the command SEARCH_TYPE=CONTINUOUS and SEARCH_TYPE=DISCRETE. For SEARCH_TYPE=CS_MULTI, the command SEARCH_DIR is not necessary. The direction of search refers to the relevant coordinate direction of the CS. A positive (negative) symbol means a search in a positive (negative) coordinate direction.
SEARCH_LEN is compulsory for the command SEARCH_TYPE=CONTINUOUS and SEARCH_TYPE=DISCRETE. For SEARCH_TYPE=CS_MULTI, the command SEARCH_LEN is not necessary. The length of the search is a general length and can also be an angle measured in degrees in the case of a cylindrical or spherical coordinate system. The length of the search must also be positive. It is recommended to choose a larger search length as the relevant tolerance.
DISCRETE_LEN is compulsory for the command SEARCH_TYPE=DISCRETE. For SEARCH_TYPE=CONTINUOUS and SEARCH_TYPE=CS_MULTI, the command DISCRETE_LEN is not necessary. The discrete length is a general length and can also be an angle measured in degrees in the case of a cylindrical or spherical coordinate system. The discrete length must be positive. It is recommended that the discrete length is smaller than the search length and larger than the relevant tolerance.
SEARCH_CS is compulsory for the command SEARCH_TYPE=CS_MULTI. For SEARCH_TYPE=CONTINUOUS and SEARCH_TYPE=DISCRETE, the command SEARCH_CS is not necessary. A total of up to 32 separate SEARCH_CS entries can be accepted. The second to the 32th entry is optional. It is recommended that all coordinate systems CS and SEARCH_CS are the same type, that is either Cartesian, cylindrical, or spherical.
Note: Using the command DVCON_AUTO_SHAPE, DVCON_SHAPE entries for node groups with the same name log can be generated automatically.
