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.
