163- The solver sets up the transport problem by importing a fixed velocity field
164- from the last time step and solving the transport of a scalar, beta, in the
165- presence of the velocity, beta being also subject to diffusion characterised
166- by a fixed proportionality constant, gamma. The solver is conceptually similar
167- to the built-in scalarTransportFoam, except it solves a steady-state problem.
168- Key things to note are 1) the syntax behind the scalar transport equation
169- 2) how OpenFOAM translates the syntax into specific operations and associates
170- them with entries in system/fvSolution and system/fvSchemes dictionaries
171- 3) inclusion of the boundary condition definitions in 0/beta into the equation
172- 4) units of the equations being solved and how OpenFOAM handles them.

174- The test case is a simple 2D square domain with fixed scalar inlets at the bottom
175- and the left-hand side. Transport takes place in the presence of a velocity
176- field convecting away from the beta inlets. Once the case is run, it is best
177- to visualise the initial conditions in the "beta" field and the solution to the
