- Mapdl.egen(itime='', ninc='', iel1='', iel2='', ieinc='', minc='', tinc='', rinc='', cinc='', sinc='', dx='', dy='', dz='', **kwargs)#
Generates elements from an existing pattern.
APDL Command: EGEN
- Parameters:
- 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. 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 type number by TINC.
- 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.
- Return type:
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.
