cscir

Mapdl.cscir(kcn='', kthet='', kphi='', **kwargs)

Locates the singularity for non-Cartesian local coordinate systems.

APDL Command: CSCIR

Parameters
kcn

Number of the local coordinate system in which singularity location is to be changed. Must be greater than 10.

kthet

Theta singularity location for cylindrical, spherical, and toroidal systems:

0 - Singularity at ±180°.

1 - Singularity at 0° (360°).

kphi

Phi singularity location for toroidal systems:

0 - Singularity in phi direction at ±180°.

1 - Singularity in phi direction at 0° (360°).

Notes

Continuous closed surfaces (circles, cylinders, spheres, etc.) have a singularity (discontinuity) at θ = ±180°. For local cylindrical, spherical, and toroidal coordinate systems, this singularity location may be changed to 0° (360°).

An additional, similar singularity occurs in the toroidal coordinate system at: Φ = ±180° and can be moved with KPHI. Additional singularities occur in the spherical coordinate system at: Φ = ±90°, but cannot be moved.

This command is valid in any processor.
