Good input for sure. I think being able to write code should be considered as an asset when looking for a CFD position (because of the knowledge of theory it requires), but certainly isn't the only thing that's necessary. I probably wouldn't hire someone for a position using commercial codes if coding is the ONLY thing they have done in CFD, for the reasons you mentioned. I think a combination of coding and using other codes is ideal. I think someone is more adaptable to other codes if they have experienced coding themselves.

do what you want to do, and you can spend some time on cfl3d code, it can give you a lot knowledges.

Richard, CFD3D is restricted. http://cfl3d.larc.nasa.gov/ Since your location reads "China" I assume you do not have permission to use CFL3D.

Edit: I assume the source code is marked as restricted and if you have read this you would know it.

although cfl3d is very famous, i haven't read it. there are some open code in china, such as opencfd. and it's very famous in china. have you read it? everyone can read it, (^_^)
