- Mapdl.cscir(kcn='', kthet='', kphi='', **kwargs)¶
Locates the singularity for non-Cartesian local coordinate systems.
APDL Command: CSCIR
Number of the local coordinate system in which singularity location is to be changed. Must be greater than 10.
Theta singularity location for cylindrical, spherical, and toroidal systems:
0 - Singularity at ±180°.
1 - Singularity at 0° (360°).
Phi singularity location for toroidal systems:
0 - Singularity in phi direction at ±180°.
1 - Singularity in phi direction at 0° (360°).
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.
