Many General Aviation pilots have a need to establish the lift distribution on the wings My foray into CFD has been to try and ascertain the lift distribution and then modify the wingtip 3D model - perhaps honer and outboard airfoil section to improve low speed handling and reduce induced drag . The second task is to look at the flow to determine the optimum position for stall strips on a laminar flow wing .

All of this happens between 70 KTS and 200 KTS.

I have been told by test pilots and wind tunnel folk that CFD is a mathematical attempt to simulate nature and requires an excellent Mesh flow field before the solver can crunch the numbers . They recommend switching off the computer as in their opinion CFD near the stall and turbulent simulation and analysis is years off ? There advice is go and fly the plane with tufts and then rinse and repeat .

Are there any plans to do an A-Z tutorial from the 3D model --> Mesh generation --> solver --> Paraview results and interpretation thereof. This would be a really useful resource to the community and could be used in university courses . Neophytes like me have cursory knowledge of the toolchain but know what we are trying to get out at the end . Often the experts assume a certain expertise level , which is understandable but a step by step tutorial which details the considerations and choices at each waypoint in the process would be great .

I do apologize for all my posts but they are all aimed at achieving this end point . Yes Paraview has its own forum as does point-wise but I can not find the A-Z of a project from conception to interpretation of the output . connecting the dots in the toolchain is really challenging as most of the projects seem to be at high mach numbers .

Hi,

The only thing that I can suggest you is reading the following book and making CFD-based simulation experiences for yourself. Other fellow might have any other useful suggestions, links, or lectures.

Good Luck,

Hey Hedley,
Yeah there are plans for an example around this tool chain. Stay tuned around the end of the summer.
