ksymm

Mapdl.ksymm(ncomp='', np1='', np2='', ninc='', kinc='', noelem='', imove='', **kwargs)

Generates a reflected set of keypoints.

APDL Command: KSYMM

Parameters
  • ncomp

    Symmetry key:

    X - X (or R) symmetry (default).

    Y - Y (or θ) symmetry.

    Z - Z (or Φ) symmetry.

  • np1 – Reflect keypoints from pattern beginning with NP1 to NP2 (defaults to NP1) in steps of NINC (defaults to 1). If NP1 = ALL, NP2 and NINC are ignored and pattern is all selected keypoints [KSEL]. If Ncomp = 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 – Reflect keypoints from pattern beginning with NP1 to NP2 (defaults to NP1) in steps of NINC (defaults to 1). If NP1 = ALL, NP2 and NINC are ignored and pattern is all selected keypoints [KSEL]. If Ncomp = 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 – Reflect keypoints from pattern beginning with NP1 to NP2 (defaults to NP1) in steps of NINC (defaults to 1). If NP1 = ALL, NP2 and NINC are ignored and pattern is all selected keypoints [KSEL]. If Ncomp = 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).

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

  • noelem

    Specifies whether nodes and elements 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.

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

    (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 a reflected set of keypoints (and corresponding mesh) from a given keypoint pattern by a symmetry reflection (see analogous node symmetry command, NSYM). The MAT, TYPE, REAL, and ESYS attributes are based upon the keypoints in the pattern and not upon the current settings. Reflection is done in the active coordinate system by changing a particular coordinate sign. Keypoints in the pattern may have been generated in any coordinate system. However, solid modeling in a toroidal coordinate system is not recommended.
