Selects a subset of volumes.
Label identifying the type of volume select:
Select a new set (default).
Reselect a set from the current set.
Additionally select a set and extend the current set.
Unselect a set from the current set.
Restore the full set.
Unselect the full set.
Invert the current set (selected becomes unselected and vice versa).
Display the current select status.
The following fields are used only with
S, R, A, or U:
Label identifying data. Valid item labels are shown in the
table below. Some items also require a component label. If
PICK (or simply “P”), graphical picking is enabled and all remaining
command fields are ignored (valid only in the GUI). Defaults to VOLU.
Component of the item (if required). Valid component labels are shown in the table below.
Minimum value of item range. Ranges are volume numbers, coordinate
values, attribute numbers, etc., as appropriate for the item. A component
name (as specified on the CM command) may also be substituted
Item = MAT, TYPE, REAL, or ESYS and
VMIN is positive, the absolute value of
compared against the range for selection; if
negative, the signed value of
Item is compared.
See the VLIST command for a discussion of signed attributes.
Maximum value of item range.
Value increment within range. Used only with integer ranges
(such as for volume numbers). Defaults to 1.
Specifies whether only volumes are to be selected:
Select volumes only.
Select volumes, as well as keypoints, lines,
areas, nodes, and elements associated with selected volumes. Valid only with
Selects volumes based on values of a labeled item and component. For example, to select a new set of volumes based on volume numbers 1 through 7, use VSEL,S,VOLU,,1,7. The subset is used when the ALL label is entered (or implied) on other commands, such as VLIST,ALL. Only data identified by volume number are selected. Data are flagged as selected and unselected; no data are actually deleted from the database.
This command is valid in any processor.
For Selects based on non-integer numbers (coordinates, results, etc.),
items that are within the range VMIN-
Toler are selected. The default tolerance
based on the relative values of VMIN and VMAX as follows:
If VMIN = VMAX,
Toler = 0.005 x
If VMIN = VMAX = 0.0,
Toler = 1.0E-6.
If VMAX ≠ VMIN,
Toler = 1.0E-8
Use the SELTOL command
to override this default and specify
Table 241: VSEL - Valid Item and Component Labels
|LOC||X, Y, Z||X, Y, or Z center (picking "hot spot" location in the active coordinate system).|
|MAT||Material number associated with the volume.|
|TYPE||Element type number associated with the volume.|
|REAL||Real constant set number associated with the volume.|
|ESYS||Element coordinate system associated with the volume.|
