CoordinateSystem.clocal(kcn='', kcs='', xl='', yl='', zl='', thxy='', thyz='', thzx='', par1='', par2='', **kwargs)#

Defines a local coordinate system relative to the active coordinate system.

Mechanical APDL Command: CLOCAL

Parameters:
kcnstr

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

kcsstr

Coordinate system type:

  • 0 or CART - Cartesian

  • 1 or CYLIN - Cylindrical (circular or elliptical)

  • 2 or SPHE - Spherical (or spheroidal)

  • 3 or TORO - Toroidal

xlstr

Location (in the active coordinate system) of the origin of the new coordinate system (R, θ, Z for cylindrical, R, θ,Φ for spherical or toroidal).

ylstr

Location (in the active coordinate system) of the origin of the new coordinate system (R, θ, Z for cylindrical, R, θ,Φ for spherical or toroidal).

zlstr

Location (in the active coordinate system) of the origin of the new coordinate system (R, θ, Z for cylindrical, R, θ,Φ for spherical or toroidal).

thxystr

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

thyzstr

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

thzxstr

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

par1str

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.

par2str

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 and activates a local coordinate system by origin location and orientation angles relative to the active coordinate system. This local system becomes the active coordinate system, and is automatically aligned with the active system (that is, x is radial if a cylindrical system is active, etc.). Nonzero rotation angles (degrees) are relative to this automatic rotation. See the cs, cskp, cswpla, and local commands for alternate definitions. Local coordinate systems may be displayed with the psymb command.

This command is valid in any processor.
