Dear all of u,

i am looking for a 3D panel method. The problem is that there are so many ( Cmarc, cosmos, newpan, panair, Vsaero...) that i do not know which one to use.

Could u please tell me which one are good with there advantages and inconvenients and prices. I am looking forward a 3D panel method for the computation of external aerodynamic problems for low subsonic airplanes.

Thank you by advance for your help and consideration. Yours faithfully, Sam.

Hi sam,

You must be more specific about the price you are ready to give.Panair is a pretty good hi-order panel method (steady analysis) with a reasonable price.Vsaero and newpan are the 2 best tools in this section (but Ithink too expensive.I am using panel method and because I didn't have the money I had to write my own source with pretty good results.

It's your choice
