    16881688In case of non-cyclic lateral boundary conditions, radiation boundary conditions are used for the velocity components at the outflow boundary.
    1689 By setting [#use_cmax use_cmax] = ''.T.'', the maximum phase velocity that ensures numerical stability (CFL-condition) is used in order that the radiation boundary conditions are simplified in this way that the phase velocity must not be calculated after every time step.
     1689If use_cmax is set to ''.T.'', the phase velocity is set to the maximum value that ensures numerical stability (CFL-condition). Thus, the radiation boundary conditions are simplified in this way that the phase velocity must not be calculated.
    16901690
    16911691Setting [#use_cmax use_cmax] = ''.F.'', the phase velocity is calculated after Orlanski (1976) after every time step and averaged along the outflow.
