How to generate the Cartesian grid

wyuanding · November 22, 2011, 10:43

Hi CFDer guys,I want to generate Cartesian grid,does anyone use program code to generate the Cartesian Grid ?Can you give me some advise or some code ?
I try a lot to write program codeb by C++ to implement the Cartesian mesh generation , but I lost myself ,I donn't know how to write the code .So I appreciate you guys can help me and if possible,please give me the code to generate the Cartesian mesh.

Thank you so much! Now I feel like that I was at sea without dirctions.

I look forward to seeing you guys as my sunshine to take me in the right direction.

Thank you again!

HI

I dont understand the difficulty here.Or maybe I haven't understood your doubt correctly.. All you have to do is generate some x and y co-ordinate values to each grid point right?

something like:

delx=.5;

for i=1:1:10

x(i+1)=x(i)+delx;

end

Thanks
Manu
