flow360.AxisymmetricRefinement

class AxisymmetricRefinement

Bases: CylindricalRefinementBase

• The mesh inside the AxisymmetricRefinement is semi-structured.

• The AxisymmetricRefinement cannot enclose/intersect with other objects.

• Users could create a donut-shape AxisymmetricRefinement and place their hub/centerbody in the middle.

• AxisymmetricRefinement can be used for resolving the strong flow gradient

  along the axial direction for the actuator or BET disks.

• The spacings along the axial, radial and circumferential directions can be adjusted independently.

Example

>>> fl.AxisymmetricRefinement(
...     entities=[cylinder],
...     spacing_axial=1e-4,
...     spacing_radial=0.3*fl.u.cm,
...     spacing_circumferential=5*fl.u.mm
... )
