26 
27 Description
28  Calculates and writes out the time taken for a particle to travel from an
29  inlet to the location. Solves the following equation when incompressible:
30  \f[
31  \div (\phi t) = 1
32  \f]
33  where:
34  \vartable
35  t | Age [s]
36  \phi | Volumetric flux [m^3/s]
37  \endvartable
38  Boundary conditions are generated automatically as zeroGradient on all
39  walls and inletOutlet everywhere else.
40 
41 Usage
42  \table
43  Property | Description | Required | Default value
44  phi | The name of the flux field | no | phi
45  rho | The name of the density field | no | rho
46  nCorr | The maximum number of correctors | no | 5
47  schemesField | The name of the field from which schemes are taken | \\
48  no | age
49  diffusion | Switch to turn on/off the diffusion term | no | off
50  tolerance | Solver residual control | no | 1e-5
