Greetings! I have provided inputs for SWASH, but unfortunately some errors occurred after running the program. Can you advise me on how to resolve these issues? Just to clarify, my bathymetry data does not contain any negative values and My grids are rectangular.
the error was:
0.482E+00 m/s
** Error : nonzero relative vertical velocity at surface in (m,n)=( 1, 152); omega = 0.375E+00 m/s
** Error : nonzero relative vertical velocity at surface in (m,n)=( 1, 153); omega = 0.236E+00 m/s
** Error : nonzero relative vertical velocity at surface in (m,n)=( 1, 154); omega = 0.771E-01 m/s
** Warning : water depth is negative in (m,n)=( 1, 166); water depth = -4.27 mm
