flow360.RotationCylinder

class RotationCylinder

Bases: RotationVolume

Deprecated since version Use: RotationVolume instead. This class is maintained for backward compatibility but will be removed in a future version.

RotationCylinder creates a rotation volume mesh using cylindrical entities.

• The mesh on RotationCylinder is guaranteed to be concentric.

• The RotationCylinder is designed to enclose other objects, but it can’t intersect with other objects.

• Users could create a donut-shape RotationCylinder and put their stationary centerbody in the middle.

• This type of volume zone can be used to generate volume zone compatible with Rotation model.

Note

RotationVolume now supports both Cylinder and AxisymmetricBody entities. Please migrate to using RotationVolume directly.

Example

>>> fl.RotationCylinder(
...     name="RotationCylinder",
...     spacing_axial=0.5*fl.u.m,
...     spacing_circumferential=0.3*fl.u.m,
...     spacing_radial=1.5*fl.u.m,
...     entities=cylinder
... )
