Changes since 1.3: +38 -26 lines
changes for new "icedyn" test:
- compile seaice & exf pkgs
- increase Olx,Oly to 4 (to use Flux-Limiter advection scheme on CS-grid)

10 C *==========================================================*
11 C | SIZE.h Declare size of underlying computational grid.
12 C *==========================================================*
13 C | The design here support a three-dimensional model grid
14 C | with indices I,J and K. The three-dimensional domain
15 C | is comprised of nPx*nSx blocks of size sNx along one axis
16 C | nPy*nSy blocks of size sNy along another axis and one
17 C | block of size Nz along the final axis.
18 C | Blocks have overlap regions of size OLx and OLy along the
19 C | dimensions that are subdivided.

46 C-- Note: the 4 test-experiments (input, input.thsice, input.viscA4 and
47 C input.icedyn ) have different minimum Overlap-size requirement:
48 C input & input.thsice : work with Olx=Oly=2 (= absolute minimum size) ;
49 C input.viscA4 : needs at least Olx=Oly=3 (for biharmonic viscosity) ;
50 C input.icedyn : needs at least Olx=Oly=4 (CS-grid multidimensional Advect.)
