ENH: add generalised log-law type ground-normal inflow boundary conditions for wind velocity and turbulence quantities for homogeneous, two-dimensional, dry-air, equilibrium and neutral atmospheric boundary layer (ABL) modelling ENH: remove `zGround` entry, which is now automatically computed ENH: add `displacement height` entry, `d` ENH: add generalised atmBoundaryLayerInletOmega boundary condition ENH: add a verification case for atmBoundaryLayerInlet BCs DOC: improve atmBoundaryLayerInlet header documentation BUG: fix value-entry behaviour in atmBoundaryLayerInlet (fixes #1578) Without this change: - for serial-parallel computations, if `value` entry is available in an `atmBoundaryLayerInlet` BC, the theoretical ABL profile expressions are not computed, and the `value` entry content is used as a profile data - for parallel computations, if `value` entry is not available, `decomposePar` could not be executed. With this change: - assuming `value` entry is always be present, the use of `value` entry for the ABL profile specification is determined by a flag `initABL` - the default value of the optional flag `initABL` is `true`, but whenever `initABL=true` is executed, `initABL` is overwritten as `false` for the subsequent runs, so that `value` entry can be safely used.
