1 
Change log for branch "pre38". 
2 

3 
o cosine(latitude) scaling of viscosity and diffusion 
4 
 moved declaration of "cosFac" from calc_mom_rhs.F to GRID.h 
5 
 now calculated in ini_spherical_grid.F (set to 1 in ini_cartesian_grid.F) 
6 
 "Method III" (preferred) available for biharmonic term 
7 
 anisotropic (preferred) scaling available 
8 
 added scaling for diffusion (same features as for viscosity above) 
9 
x thought for the future: lateral GM/Redi fluxes are currently scaled. 
10 
If we scale them we would have to scale the other tensor components 
11 
in order to retain the adiabatic property of scheme. 
12 
o combined initializations of G's and other timestepping arrays 
13 
 created ini_garrays.F to initialize G's to zero 
14 
 combined uVel + vVel initialization into ini_vels.F 
15 
 deleted ini_uvel.F + ini_vvel.F 
16 
 removed ini_gw.F since no longer necessary 
17 
o rearranged order of arrays in /GRID_R/ in GRID.h 
18 
g77 suddenly started complaining about padding. Odd but SGI concurred! 
19 
o fixed CPP_EEOPTIONS.h in hs94.128x64x5 
20 
o moved cg2d solver into pkg/cg2d 
21 
 added CPP flag for using "regular" overlaps instead of Olx=Oly=1
