- Mapdl.cs(kcn='', kcs='', norig='', nxax='', nxypl='', par1='', par2='', **kwargs)#
Defines a local coordinate system by three node locations.
Mechanical APDL Command: CS
- Parameters:
- kcn
str
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
str
Coordinate system type:
0 or CART
- Cartesian1 or CYLIN
- Cylindrical (circular or elliptical)2 or SPHE
- Spherical (or spheroidal)3 or TORO
- Toroidal
- norig
str
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
str
Node defining the positive x-axis orientation of this coordinate system.
- nxypl
str
Node defining the x-y plane (with
NORIG
andNXAX
) in the first or second quadrant of this coordinate system.- par1
str
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)). IfKCS
= 3,PAR1
is the major radius of the torus.- par2
str
Used for spheroidal systems. If
KCS
= 2,PAR2
= ratio of ellipse Z-axis radius to X-axis radius (defaults to 1.0 (circle)).
- kcn
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.
