Test cases of different levels of complexity
 
Hi,

My aim is to simulate the flow past an airfoil. I'm now trying to test my structured FVM code for any errors.

Initially, I wrote a cartesian code and used the well known lid driven cavity. I then moved on to write the structured code and I've used a skewed lid driven cavity test by Erturk (www.cavityflow.com).

Both worked well. Should I go on directly to simulate an airfoil? Or are there any test cases which I can do before going to the airfoil problem?

Thanks

Re: Test cases of different levels of complexity
 
You don't say whether your code is inviscid/viscous compressible/incompressible.

You should try to run the code for some benchmark cases (cases for which you can obtain analytic or semi-analytic results). Examples include; compression over a wedge, expansion over a backwards facing wedge; williams airfoil and williams multi-element airfoil; laminar flow over flat plate; turbulent flow over flat plate. The NPARC V&V website is a good place to start for more details/data.
