1    Example: "4 Layer Double Gyre"
2    ==============================
3    
4    To apply the changes to the default configuration of MITgcmUV:
5      cp ../verification/exp1/code/SIZE.h ../model/inc/
6      cp ../verification/exp1/code/CPP_OPTIONS.h ../model/inc/
7      cp ../verification/exp1/code/CPP_EEOPTIONS.h ../eesupp/inc/
8    
9    Configure and compile the code:
10      cd bin
11      ../tools/genmake -makefile
12      make depend
13      make
14    
15    To run:
16      cd ../exe
17      cp ../verification/exp1/input/* .
18      dmpirun -np 4 mitgcmuv  ( Digital )
19    
20    There is comparison output in two directories:
21     ../verification/exp1/results
22     ../verification/exp1/results.oldcode
23    
24    To obtain the "oldcode" numbers make the following changes
25    to the older code:
26    CPP_OPTIONS.h must have
27      #define OLD_ADV_BCS
28      #define OLD_UV_GEOMETRY
29    calc_mom_rhs.F must have
30      #define NO_LATERAL_SLIP
31      #define NO_BOTTOM_SLIP
32    ini_depths.F must have the "island" removed.
33    
34    Comments:
35    The input data is real*8 and can be generated with the supplied
36    matlab script gendata.m  to change the input precision to
37    real*4 change readBinaryPrec=32 in data as well as in gendata.m
Legend:
Removed from v.1.1
