local

Mapdl.local(kcn='', kcs='', xc='', yc='', zc='', thxy='', thyz='', thzx='', par1='', par2='', **kwargs)

Defines a local coordinate system by a location and orientation.

APDL Command: LOCAL

Parameters
  • kcn – Arbitrary reference number assigned to this coordinate system. Must be greater than 10. A coordinate system previously defined with this number will be redefined.

  • kcs

    Coordinate system type:

    0 or CART - Cartesian

    1 or CYLIN - Cylindrical (circular or elliptical)

    2 or SPHE - Spherical (or spheroidal)

    3 or TORO - Toroidal

  • xc – Location (in the global Cartesian coordinate system) of the origin of the new coordinate system.

  • yc – Location (in the global Cartesian coordinate system) of the origin of the new coordinate system.

  • zc – Location (in the global Cartesian coordinate system) of the origin of the new coordinate system.

  • thxy – First rotation about local Z (positive X toward Y).

  • thyz – Second rotation about local X (positive Y toward Z).

  • thzx – Third rotation about local Y (positive Z toward X).

  • par1 – Used for elliptical, spheroidal, or toroidal systems. If KCS = 1 or 2, PAR1 is the ratio of the ellipse Y-axis radius to X-axis radius (defaults to 1.0 (circle)). If KCS = 3, PAR1 is the major radius of the torus.

  • par2 – Used for spheroidal systems. If KCS = 2, PAR2 = ratio of ellipse Z-axis radius to X-axis radius (defaults to 1.0 (circle)).

Notes

Defines a local coordinate system by origin location and orientation angles. The local coordinate system is parallel to the global Cartesian system unless rotated. Rotation angles are in degrees and redefine any previous rotation angles. See the CLOCAL, CS, CSWPLA, and CSKP commands for alternate definitions. This local system becomes the active coordinate system [CSYS]. Local coordinate systems may be displayed with the /PSYMB command.

This command is valid in any processor.
