CSCIR

CSCIR, KCN, KTHET, KPHI
Locates the singularity for non-Cartesian local coordinate systems.

Valid Products: Pro | Premium | Enterprise | PrepPost | Solver | AS add-on

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°).

Command Default

Singularities at ±180°.

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.
