You must install Array Viewer to run the program: http://h18009.www1.hp.com/fortran/aview/getviewer.html

3. 2D Boundary flow ( I have tested the program, it works)

cgn5930fluid\bflow.for

( To compile this program: in Unix, use "f77 bflow.for -o bflow"

then it create a excutable file: bflow,

type 'bflow' to run the program, you will be asked to input data.

Input data: Rho=1000, AMU=1

Others: dx, NDX, dy, Ndy

Test Case: dx=5, dy=1, Ndx=10, Ndy=10, rho=1000, amu=1

4. sample Matlab program for vector plot

% vplot.m

% example to plot u and w veclor, uq.txt is sample u data, wq.txt is sample w data

% for more information, type "help quiver"; or "help contourf" in matlab

load uq.txt; load wq.txt;

[x,z]=meshgrid(2:31,-2:-1:-35);

[c,h] = contourf(x,z,uq); clabel(c,h), colorbar

quiver(x,z,uq,wq)
