kgen

Mapdl.kgen(itime='', np1='', np2='', ninc='', dx='', dy='', dz='', kinc='', noelem='', imove='', **kwargs)

Generates additional keypoints from a pattern of keypoints.

APDL Command: KGEN

Parameters
  • itime – Do this generation operation a total of ITIME times, incrementing all keypoints in the given pattern automatically (or by KINC) each time after the first. ITIME must be more than 1 for generation to occur.

  • np1 – Generate keypoints from the pattern of keypoints beginning with NP1 to NP2 (defaults to NP1) in steps of NINC (defaults to 1). If NP1 = ALL, NP2 and NINC are ignored and the pattern is all selected keypoints [KSEL]. If NP1 is negative, NP2 and NINC are ignored and the last |NP1| keypoints (in sequence from the highest keypoint number) are used as the pattern to be repeated. If NP1 = 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 NP1 (NP2 and NINC are ignored).

  • np2 – Generate keypoints from the pattern of keypoints beginning with NP1 to NP2 (defaults to NP1) in steps of NINC (defaults to 1). If NP1 = ALL, NP2 and NINC are ignored and the pattern is all selected keypoints [KSEL]. If NP1 is negative, NP2 and NINC are ignored and the last |NP1| keypoints (in sequence from the highest keypoint number) are used as the pattern to be repeated. If NP1 = 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 NP1 (NP2 and NINC are ignored).

  • ninc – Generate keypoints from the pattern of keypoints beginning with NP1 to NP2 (defaults to NP1) in steps of NINC (defaults to 1). If NP1 = ALL, NP2 and NINC are ignored and the pattern is all selected keypoints [KSEL]. If NP1 is negative, NP2 and NINC are ignored and the last |NP1| keypoints (in sequence from the highest keypoint number) are used as the pattern to be repeated. If NP1 = 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 NP1 (NP2 and NINC are ignored).

  • dx – Keypoint location increments in the active coordinate system (DR, Dθ, DZ for cylindrical, DR, Dθ, DΦ for spherical).

  • dy – Keypoint location increments in the active coordinate system (DR, Dθ, DZ for cylindrical, DR, Dθ, DΦ for spherical).

  • dz – Keypoint location increments in the active coordinate system (DR, Dθ, DZ for cylindrical, DR, Dθ, DΦ for spherical).

  • kinc – Keypoint increment between generated sets. If zero, the lowest available keypoint numbers are assigned [NUMSTR].

  • noelem

    Specifies if elements and nodes are also to be generated:

    0 - Generate nodes and point elements associated with the original keypoints, if

    they exist.

    1 - Do not generate nodes and elements.

  • imove

    Specifies whether keypoints will be moved or newly defined:

    0 - Generate additional keypoints as requested with the ITIME argument.

    1 - Move original keypoints to new position retaining the same keypoint numbers

    (ITIME, KINC, and NOELEM are ignored). Valid only if the old keypoints are no longer needed at their original positions. Corresponding meshed items are also moved if not needed at their original position.

Notes

Generates additional keypoints (and corresponding mesh) from a given keypoint pattern. The MAT, TYPE, REAL, and ESYS attributes are based upon the keypoints in the pattern and not upon the current settings. Generation is done in the active coordinate system. Keypoints in the pattern may have been defined in any coordinate system. However, solid modeling in a toroidal coordinate system is not recommended.
