# FlowField¶

class acoular.environments.FlowField

Bases: traits.has_traits.HasPrivateTraits

An abstract base class for a spatial flow field.

v(xx)

Provides the flow field as a function of the location. This is implemented here for the possibly most simple case: a quiescent fluid.

Parameters
xxarray of floats of shape (3, )

Location in the fluid for which to provide the data.

Returns
tuple with two elements

The first element in the tuple is the velocity vector and the second is the Jacobian of the velocity vector field, both at the given location.
