Specifies the divisions and spacing ratio on unmeshed lines.
NL1
Number of the line to be modified. If ALL, modify all selected lines (LSEL). If
NL1
= P, graphical picking is enabled and all remaining command fields are ignored (valid only in the GUI). A component name may also be substituted forNL1
.SIZE
If
NDIV
is blank,SIZE
is the division (element edge) length. The number of divisions is automatically calculated from the line length (rounded upward to next integer). IfSIZE
is zero (or blank), useANGSIZ
orNDIV
.ANGSIZ
The division arc (in degrees) spanned by the element edge (except for straight lines, which always result in one division). The number of divisions is automatically calculated from the line length (rounded upward to next integer).
NDIV
If positive,
NDIV
is the number of element divisions per line. If -1 (andKFORC
= 1),NDIV
is assumed to be zero element divisions per line. TARGE169 with a rigid specification ignoresNDIV
and will always mesh with one element division.SPACE
Spacing ratio. If positive, nominal ratio of last division size to first division size (if > 1.0, sizes increase, if < 1.0, sizes decrease). If negative, |
SPACE
| is nominal ratio of center division(s) size to end divisions size. Ratio defaults to 1.0 (uniform spacing). For layer-meshing, a value of 1.0 normally is used. IfSPACE
= FREE, ratio is determined by other considerationsKFORC

—
Modify only selected lines having undefined (zero) divisions.
1
—
Modify all selected lines.
2
—
Modify only selected lines having fewer divisions (including zero) than specified with this command.
3
—
Modify only selected lines having more divisions than specified with this command.

Modify only nonzero settings for

Layer-meshing control parameter. Distance which defines the thickness of the inner mesh layer,
LAYER1
. Elements in this layer are uniformly-sized with edge lengths equal to the specified element size for the line (either throughSIZE
or line-length/NDIV
). A positive value forLAYER1
is interpreted as an absolute length, while a negative value in interpreted as a multiplier on the specified element size for the line. As a general rule, the resulting thickness of the inner mesh layer should be greater than or equal to the specified element size for the line. IfLAYER1
= OFF, layer-meshing control settings are cleared for the selected lines. The default value is 0.0LAYER2
Layer-meshing control parameter. Distance which defines the thickness of the outer mesh layer,
LAYER2
. Elements in this layer transition in size from those inLAYER1
to the global element size. A positive value ofLAYER2
is interpreted as an absolute length, while a negative value is interpreted as a mesh transition factor. A value ofLAYER2
= -2 would indicate that elements should approximately double in size as the mesh progresses normal toLAYER1
. The default value is 0.0.KYNDIV
0, No, and Off means that SmartSizing cannot override specified divisions and spacing ratios. Mapped mesh fails if divisions do not match. This defines the specification as "hard".
1, Yes, and On means that SmartSizing can override specified divisions and spacing ratios for curvature or proximity. Mapped meshing can override divisions to obtain required matching divisions. This defines the specification as" soft".
Notes
Defines the number of divisions and the spacing ratio on selected lines. Lines with previously specified divisions may also be changed.
This command is also valid for rezoning.
