cs#

Mapdl.cs(kcn='', kcs='', norig='', nxax='', nxypl='', par1='', par2='', **kwargs)#

Defines a local coordinate system by three node locations.

APDL Command: CS

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

norig

Node defining the origin of this coordinate system. If NORIG = P, graphical picking is enabled and all remaining command fields are ignored (valid only in the GUI).

nxax

Node defining the positive x-axis orientation of this coordinate system.

nxypl

Node defining the x-y plane (with NORIG and NXAX) in the first or second quadrant of this coordinate system.

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 and activates a local right-handed coordinate system by specifying three existing nodes: to locate the origin, to locate the positive x-axis, and to define the positive x-y plane. This local system becomes the active coordinate system. See the CLOCAL, 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.
