Example "double-gyre" experiment |
Example: "4 Layer Double Gyre" |
| 2 |
This directory contains chnages that reconfigure the baseline MITgcmUV |
============================== |
|
setup for a double-gyre beta plane experiment. |
|
|
|
|
|
To apply the chagesto the baseline configuration of MITgcmUV |
|
|
1. Install baseline code |
|
|
2. cd verification/exp1 |
|
|
3. ./setup.sh |
|
|
4. cd ../../bin |
|
|
5. make |
|
|
6. dmpirun -np 4 ../exe/mitgcmuv ( Digital ) |
|
| 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 |
