C-Grid Generation Around an Arifoil-Matlab

tawhite88 · April 29, 2011, 04:18

I'm looking to develop a Matlab code to generate a c-grid around an airfoil with clustering near the surface and wake region (trialing edge). I need to do this using an algebraic method. Then from here I'm to generate the same thing using an elliptic scheme with no clustering. I really have no experience doing mesh/grid generation in Matlab. Does anyone have any sample codes I could take a look at or any links to sites that have information on how to get started on this? Thank you for any help.

There is always a book ...

Fletcher - "Computational Techniques for Fluid Dynamics", vol II

see chapter 13, the book also has a Fortran code for algebraic grid generation (you can translate this to Matlab easily).

Thanks for the tip this looks like it will be a helpful read. Unfortunately I've never used Fortran before so "easily" might be too strong of a word, but I'll try to stumble through it. Unless there happens to be matlab version out ther. I'd love to see it XD. Thanks again.

Does anyone have some sort of sample code or at least the general steps I should go through to write one in Matlab. I'm afraid I'm lost when it comes to half the stuff in the Fortran code in the book you recommended.
