ANSYS如何选择一个范围内的所有体（使用vsel,s,loc,x）
因为需要在柱体坐标下选择一个柱状体内所有的体，可是每次都不能选择正确，请问应该如何设置！其中vsel,s,loc,x的x对应的是柱体坐标的半径...

Type
Label identifying the type of volume select:
S — Select a new set (default).
R — Reselect a set from the current set.
A — Additionally select a set and extend the current set.
U — Unselect a set from the current set.
ALL — Restore the full set.
NONE — Unselect the full set.
INVE — Invert the current set (selected becomes unselected and vice versa).
STAT — Display the current select status.
The following fields are used only with Type = S, R, A, or U:
Item
Label identifying data. Valid item labels are shown in the table below. 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 VOLU.
Comp
Component of the item (if required). Valid component labels are shown in the table below.
VMIN
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 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 VLIST command for a discussion of signed attributes.
VMAX
Maximum value of item range. VMAX defaults to VMIN.
VINC
Value increment within range. Used only with integer ranges (such as for volume numbers). Defaults to 1. VINC cannot be negative.
KSWP
Specifies whether only volumes are to be selected:
0 — Select volumes only.
1 — Select volumes, as well as keypoints, lines, areas, nodes, and elements associated with selected volumes. Valid only with Type = S.
Command Default
All volumes are selected.
Notes
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 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.
VSEL - Valid Item and Component Labels
VSELType, Item, Comp, VMIN, VMAX, VINC, KABS
Item Comp Description
VOLU Volume number.
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.
