209      If no file names are provided, the velocity is initialised to zero.
210      The initial vertical velocity is always derived from the horizontal velocity
211      using the continuity equation, even in the case of non-hydrostatic simulation
212      (see, e.g.: {\it tutorial\_deep\_convection/input/data}).

214      In the case of a restart (from the end of a previous simulation),
215      the velocity field is read from a pickup file
216      (see section on simulation control parameters)
217      and the initial velocity files are ignored.
