摘要: Abstract The ADIFOR2.0 automatic differentiator is applied to the FLOMGEM flow solver along with grid generator HYPERG2. an advanced Navier-Stokes CFD code for airfoil computations, which employs multigrid method. HYPERG2 a two-dimensional hyperbolic generating C-mesh. Both non-geometric and geometric sensitivity derivative codes are obtained. derivatives via differentiation presented compared divided difference generated derivatives. study shows that method gives accurate values in efficient manner.
