Body fitted Grid
 
Hello all, I need a 2D grid generator which will generate a body fitted grid around simple geometries like airfoils,cylinders,etc., to simulate Viscous flows.

If suggestion in the form of websites where we can download is also appreciable Thanx

(1). Joe Thompson's book of "numerical grid generation" has Fortran codes attached to do various 2-D grid generation. (2). The book is free on Internet, see resources section. (3). Always surf the resources section first, before you ask a question. It will save you a lot of time.

I don't know how soon you need this grid generator, probably tomorrow, right? I am planning to put such a program on my website - www.cfd4pc.com - for download within 6-8 weeks. So far only O-grid, elliptically or algebraically generated. C-grid, which is needed for viscous airfoil analysis will come later. O-grid works fine on cylinders, circular or elliptical, anything without a sharp trailing edge.

I'll tell you what, as soon as I have the installation file ready, I will let you know, and you can test it for me. I always need a few people to test the installation on different platforms and run the software before I publish.

I really need a2 D grid generator code
 
Dear Axel Rohde
in topic of the "I need a 2D grid generator which will generate a body fitted grid"
I really need a copy of your code and I really appreciate your help. I can not open the www.cfd4pc.com, and my email is liuzc39@yahoo.com.cn. thank you very much.

Hello,

you can search the NASA website for "hyperbolic grid" or "hyperbolic mesh" this will give you a lot of papers about how you can generate C type meshes on 2D configurations. If you need a more detailed help send me your email.
