... (1) with Lamé parameters λ ≡ 0 and constant µ > 0, and a TRACE gradient, which is generated by solving a linear elasticity mesh smoothing system with Dirichlet boundaries being the lattice sensitivities D ad J(Ω ext,k ), for the isentropic total pressure loss coefficient in relative frame of reference based on dynamic pressure is portrayed in Fig. 3. We can see additional gain of regularity in the gradient through Steklov-Poincaré representation, in particular the pronounced rise in sensitivity at the trailing edge is handled by redistributing sensitivities at the pressure side in a smooth manner, thus guaranteeing better stability of the mesh morphing ...
