4 C CPP options file for OBCS package

6 C Use this file for selecting options within the OBCS package

33 C balance barotropic velocity
34 #undef ALLOW_OBCS_BALANCE

36 C The following five CPP options are experimental and aim to deal
37 C with artifacts due to the low-frequency specification of sea-ice
38 C boundary conditions compared to the model's forcing frequency.
39 C Ice convergence at edges can cause model to blow up. The
40 C following CPP option fixes this problem at the expense of less
41 C accurate boundary conditions.

44 C Smooth the component of sea-ice velocity perpendicular to the edge.
45 #undef OBCS_SEAICE_SMOOTH_UVICE_PERP

47 C Smooth the component of sea ice velocity parallel to the edge.
48 #undef OBCS_SEAICE_SMOOTH_UVICE_PAR

50 C Smooth the tracer sea-ice variables near the edges.
