EGEN
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 byNINCeach time after the first.ITIMEmust be >1 if generation is to occur.NINCmay be positive, zero, or negative. IfDX,DY, and/orDZis specified,NINCshould be set so any existing nodes (as on NGEN) are not overwritten.IEL1,IEL2,IEINCGenerate elements from selected pattern beginning with
IEL1toIEL2(defaults toIEL1) in steps ofIEINC(defaults to 1). IfIEL1is negative,IEL2andIEINCare ignored and the last |IEL1| elements (in sequence backward from the maximum element number) are used as the pattern to be repeated. IfIEL1= ALL,IEL2andIEINCare 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(IEL2andINCare ignored).MINCIncrement material number of all elements in the given pattern by
MINCeach time after the first.TINCIncrement element type number by
TINC. The element types with incremented numbers must be defined before issuing the EGEN command.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,DZwere issued before EGEN). Zero is a valid value. If blank,DX,DY, andDZare 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.
