Generates elements from an existing pattern.

ITIME, NINC

Do 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, IEINC

Generate 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).

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, and DZ 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.
