                0042 C       been implementated in new version.

                0046 C     The following five CPP options are experimental and aim to deal
                0047 C     with artifacts due to the low-frequency specification of sea-ice
                0048 C     boundary conditions compared to the model forcing frequency.
                0049 C     Ice convergence at edges can cause model to blow up.  The
                0050 C     following CPP option fixes this problem at the expense of less
                0051 C     accurate boundary conditions.

                0056
                0057 C     Smooth the component of sea ice velocity parallel to the edge.
                0058 #undef OBCS_SEAICE_SMOOTH_UVICE_PAR

                0060 C     Compute rather than specify seaice velocities at the edges.
