    77the constant values for stage, xmomentum and ymomentum is constructed
    8 and used in the function call, e.g. {{{Dirichlet_boundary([0.2,0.,0.])}}} .

     10== How do I know which boundary tags are available? ==
     11
     12The method {{{domain.get_boundary_tags()}}} will return a list of
     13available tags for use with {{{domain.set_boundary_condition()}}}.

     15== What is the difference between file_boundary and field_boundary? ==
     16
     17The only difference is {{{field_boundary}}} will allow you to change the level of the stage height when you read in the boundary condition.
     18This is very useful when running different tide heights in the same area as you need only to convert
     19one boundary condition to a SWW file, ideally for tide height of 0m (saving disk space). Then you can
     20use {{{field_boundary}}} to read this SWW file and change the stage height (tide) on the fly depending on the scenario.
