HubbleRadialVectorField represents a vector field with vectors pointing away from the origin and a magnitude that varies with radial distance from the origin. Up to the turnover radius \((r_t \ge 0)\), the velocity is constantly accelerating. Beyond the turnover radius, the velocity is constantly decelarating. Beyond the maximum radius \((r_\mathrm{max} \ge r_t)\), the velocity is zero:
\[ v(r) = \begin{cases}\frac{r}{r_t} & \mathrm{for}\;r\le r_t \\ \left(1-\frac{r - r_t}{r_\mathrm{max}-r_t}\right) & \mathrm{for}\;r_t < r\le r_\mathrm{max} \\0 & \mathrm{for}\;r> r_\mathrm{max} \end{cases} \]
This radial magnitude dependence was presented in Das et al. 2006 (AJ, 132, 620D) as the velocity field for the biconical polar outflow in NGC1068.
When an item of this type is used, the names provided by the conditional value expression "Dimension3" are inserted into the name sets used for evaluating Boolean expressions.

Default constructor for concrete Item subclass HubbleRadialVectorField : "a Hubble flow pointing away from the origin with a constant acceleration and decelaration" .
|
overridevirtual |
This function returns the dimension of the vector field, which is 3 for this class, indicating no symmetries (the vectors point in a different direction at each position).
Implements VectorField.
|
inline |
This function returns the value of the discoverable double property maxRadius : "the maximum radius beyond which the outflow velocity is zero" .
This property represents a physical quantity of type "length" .
The minimum value for this property is "[0" .
|
overrideprotectedvirtual |
This function verifies that \(r_t \le r_\mathrm{max}\).
Reimplemented from SimulationItem.
