【Abstract】 A technique is presented for constructing a boundary conforming grid on an arbitrarily curved surface. Then as a boundary values , the Poisson’s equations can be solved to obtain a 3 D body fitted grid for CFD. A primary feature of the technique is that the grid on an arbitrarily curved surface is easy to be generated and adjusted forwardly, and remains continuous and smooth . Sample results are given for an arbitrarily curved surface and an air conditioned cockpit of a helicopter/fighter aircraft.更多还原
