Generates elements from an existing pattern.
ITIME
,NINC
Do this generation operation a total of
ITIME
s, incrementing all nodes in the given pattern byNINC
each time after the first.ITIME
must be >1 if generation is to occur.NINC
may be positive, zero, or negative. IfDX
,DY
, and/orDZ
is specified,NINC
should be set so any existing nodes (as on NGEN) are not overwritten.IEL1
,IEL2
,IEINC
Generate elements from selected pattern beginning with
IEL1
toIEL2
(defaults toIEL1
) in steps ofIEINC
(defaults to 1). IfIEL1
is negative,IEL2
andIEINC
are ignored and the last |IEL1
| elements (in sequence backward from the maximum element number) are used as the pattern to be repeated. IfIEL1
= ALL,IEL2
andIEINC
are ignored and use all selected elements (ESEL) as pattern to be repeated. IfP1
= P, graphical picking is enabled and all remaining command fields are ignored (valid only in the GUI). A component name may also be substituted forIEL1
(IEL2
andINC
are ignored).MINC
Increment material number of all elements in the given pattern by
MINC
each time after the first.TINC
Increment element type number by
TINC
. The element types with incremented numbers must be defined before issuing the EGEN command.RINC
Increment real constant table number by
RINC
.CINC
Increment element coordinate system number by
CINC
.SINC
Increment section ID number by
SINC
.DX
,DY
,DZ
Define nodes that do not already exist but are needed by generated elements (as though the NGEN,
ITIME,INC,NODE1,,,DX,DY,DZ
were issued before EGEN). Zero is a valid value. If blank,DX
,DY
, andDZ
are ignored.
Notes
A pattern may consist of any number of previously defined elements. The MAT, TYPE, REAL, ESYS, and SECNUM numbers of the new elements are based upon the elements in the pattern and not upon the current specification settings.
You can use the EGEN command to generate interface elements (INTER192, INTER193, INTER194, and INTER195) directly. However, because interface elements require that the element connectivity be started from the bottom surface, you must make sure that you use the correct element node connectivity. See the element descriptions for INTER192, INTER193, INTER194, and INTER195 for the correct element node definition.
