Use matlab to compare Eta for 6-tile and 12-tile integrations |
| 46 |
============================================================= |
| 47 |
matlab -nojvm -nosplash |
| 48 |
f1='run6/Eta.'; f2='run12/Eta.'; tm=72003; |
| 49 |
ix=.5:191.5; iy=.5:31.5; |

tmp1=readbin([f1 myint2str(tm,10) '.data'],[32*6,32]); |
| 51 |
tmp2=readbin([f2 myint2str(tm,10) '.data'],[32*6,32]); |
| 52 |
clf, subplot(211) |
| 53 |
image(ix,iy,tmp1','CDataMapping','scaled'); colorbar, grid |
| 54 |
set(gca,'ydir','normal','xtick',0:32:192,'ytick',0:16:32) |
| 55 |
title('Eta, time step 3, 6-tile integration') |
