Best book for corner/boundary grids treatment

Wen Long

Hi, CFD players:

In my experience of coding FDM programs on structured grids, I found the most of my bugs are really from treatment of boundary grids in side the domain. Like structures, blocks,,,

I think there are many tricks for getting the ghost grid values. While near corner, it's always double or even triple valued, mean we have to use one value at one direction and another in another direction. I'm really interested to see notes or books giving very detailed treatment of these tricks, such as grid numbering, data structure, stability concerns, preferable for different sets of gird systems: staggered or non-staggered, 2D or 3D...

Do you happen to have such references? I don't want books talking about general ideas, I want those giving details, just like investers yelling "no talk, show me the money", I yell "show me how you did it! Show me the code"

Thanks if you can point me somewhere. BTW, I have read Roache 1977 CFD book.

Thanks,

Wen
