Selects a subset of areas.

Compatible Products: – | Pro | Premium | Enterprise | Ent PP | Ent Solver | DYNA


Label identifying the type of 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 Type = S, R, A, or U:


Label identifying data. Valid item labels are shown in Table 117: ASEL - Valid Item and Component Labels. Some items also require a component label. If Item = PICK (or simply “P”), graphical picking is enabled and all remaining command fields are ignored (valid only in the GUI). Defaults to AREA.


Component of the item (if required). Valid component labels are shown in Table 117: ASEL - Valid Item and Component Labels.


Minimum value of item range. Ranges are area numbers, coordinate values, attribute numbers, etc., as appropriate for the item. A component name (as specified on the CM command) may also be substituted for VMIN (VMAX and VINC are ignored). If Item = MAT, TYPE, REAL, or ESYS and if VMIN is positive, the absolute value of Item is compared against the range for selection; if VMIN is negative, the signed value of Item is compared. See the ALIST command for a discussion of signed attributes.


Maximum value of item range. VMAX defaults to VMIN.


Value increment within range. Used only with integer ranges (such as for area numbers). Defaults to 1. VINC cannot be negative.


Specifies whether only areas are to be selected:



Select areas only.



Select areas, as well as keypoints, lines, nodes, and elements associated with selected areas. Valid only with Type = S.

Command Default

All areas are selected.


Selects a subset of areas. For example, to select those areas with area numbers 1 through 7, use ASEL,S,AREA,,1,7. The selected subset is then used when the ALL label is entered (or implied) on other commands, such as ALIST,ALL. Only data identified by area number are selected. Data are flagged as selected and unselected; no data are actually deleted from the database.

In a cyclic symmetry analysis, area hot spots can be modified. Consequently, the result of an area selection may be different before and after the CYCLIC command.

If Item = ACCA, the command selects only those areas that were created by concatenation. The KSWP field is processed, but the Comp, VMIN, VMAX, and VINC fields are ignored.

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 and VMAX+Toler are selected. The default tolerance Toler is based on the relative values of VMIN and VMAX as follows:

  • If VMIN = VMAX, Toler = 0.005 x VMIN.

  • If VMIN = VMAX = 0.0, Toler = 1.0E-6.

  • If VMAX ≠ VMIN, Toler = 1.0E-8 x (VMAX-VMIN).

Use the SELTOL command to override this default and specify Toler explicitly.

Table 117:  ASEL - Valid Item and Component Labels

Valid Item and Component Labels ASEL, Type Item,Comp,VMIN,VMAX,VINC,KSWP
AREA Area number.
EXT Area numbers on exterior of selected volumes (ignore remaining fields).
LOCX, Y, ZX, Y, or Z center (picking "hot spot" location in the active coordinate system).
HPT Area number (selects only areas with associated hard points).
MAT  Material number associated with the area.
TYPE Element type number associated with the area.
REAL Real constant set number associated with the area.
ESYS Element coordinate system associated with the area.
SECN Section number associated with the area.
ACCA Concatenated areas (selects only areas that were created by area concatenation [ACCAT]).
