WindTunnelFarfield

WindTunnelFarfield#

class WindTunnelFarfield[source]#

Bases: _FarfieldAllowingEnclosedEntities

Settings for analytic wind tunnel farfield generation. The user only needs to provide tunnel dimensions and floor type and dimensions, rather than a geometry.

Important: By default, the volume mesher will grow boundary layers on WindTunnelFarfield. Use PassiveSpacing to project or disable boundary layer growth.

Example

>>> fl.WindTunnelFarfield(
    width = 10 * fl.u.m,
    height = 5 * fl.u.m,
    inlet_x_position = -10 * fl.u.m,
    outlet_x_position = 20 * fl.u.m,
    floor_z_position = 0 * fl.u.m,
    floor_type = fl.CentralBelt(
        central_belt_x_range = (-1, 4) * fl.u.m,
        central_belt_width = 1.2 * fl.u.m
    )
)

Attributes

domain_type: Literal['half_body_positive_y', 'half_body_negative_y', 'full_body'], optional#

- half_body_positive_y: Trim to a half-model by slicing with the global Y=0 plane; keep the ‘+y’ side for meshing and simulation. - half_body_negative_y: Trim to a half-model by slicing with the global Y=0 plane; keep the ‘-y’ side for meshing and simulation. - full_body: Keep the full body for meshing and simulation without attempting to add symmetry planes. Warning: When using AutomatedFarfield or UserDefinedFarfield, setting domain_type overrides automatic symmetry plane detection.

Default:

None

enclosed_entities: EntityList[Surface, Cylinder, AxisymmetricBody, Sphere, CustomVolume], optional#

The surfaces/surface groups that are the interior boundaries of the farfield zone when defining custom volumes. - Only allowed when using one or more CustomZone(s) to define volume zone(s) in meshing parameters - Cylinder, AxisymmetricBody, Sphere entities must be associated with RotationVolume(s)
