For the primal solution, please refer to the Newton-ILU case above (with Nonlinear solver iterations limited to 50)

• Adjoint parameters:
  • Adjoint output: Drag
  • Patch Reconstruction H1: False
  • Hessian Scalar Type: -1 (Mach number for Hessian evaluation)
  • Nonlinear Smoother: Newton (solved to 10^-6)
  • Adjoint Smoother residual converged to 10^-6
  • Primal truth surrogate not fully converged
  • Adjoint truth fully converged
• Adaptation parameters:
  • Output Adapted: Drag
  • Anisotropy method: Hessian
  • Re-meshing method: boundary curved
  • Number of adaptation iterations: 2

  • Adaptation algorithm: Fixed-Fraction marking
    • 30% refining and 20% coarsening fractions
    • Target degree-of-freedom increase factor: 1.0
      (constant DOF)
  • Forward sensitivities are computed
    (i.e. dC_D/dα with a tangent linearization)
• Serial results:
  • Initial mesh:
    • DOF = 990
    ;
