EGEN, ITIME, NINC, IEL1, IEL2, IEINC, MINC, TINC, RINC, CINC, SINC, DX, DY, DZ
Generates elements from an existing pattern.
ITIME, NINCDo this generation operation a total of ITIMEs,
incrementing all nodes in the given pattern by NINC each
time after the first. ITIME must be >1 if generation
is to occur. NINC may be positive, zero, or negative.
If DX, DY, and/or DZ is
specified, NINC should be set so any existing nodes
(as on NGEN) are not overwritten.
IEL1, IEL2, IEINCGenerate elements from selected pattern beginning with IEL1 to IEL2 (defaults
to IEL1) in steps of IEINC (defaults
to 1). If IEL1 is negative, IEL2 and IEINC are
ignored and the last |IEL1| elements (in sequence
backward from the maximum element number) are used as the pattern to be repeated.
If IEL1 = ALL, IEL2 and IEINC are
ignored and use all selected elements [ESEL] as pattern
to be repeated. If P1 = P, graphical picking is
enabled and all remaining command fields are ignored (valid only in the GUI).
A component name may also be substituted for IEL1 (IEL2 and INC are
ignored).
MINCIncrement material number of all elements in the given pattern
by MINC each time after the first.
TINCIncrement type number by TINC.
RINCIncrement real constant table number by RINC.
CINCIncrement element coordinate system number by CINC.
SINCIncrement section ID number by SINC.
DX, DY, DZDefine 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,
and DZ are ignored.
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.
