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
- hp adaptation space
- 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. dCD/dα with a tangent linearization)
- Serial results:
- Initial mesh:
- DOF = 990
- Error estimate = 3.9138·10-4
- Drag = 5.3180·10-4
- First adaptation:
- DOF = 1008
- Error estimate = 1.9066·10-4
- Drag = 2.6942·10-4
- Second adaptation:
- DOF = 1026
- Error estimate = 1.3617·10-4
- Drag = 2.0600·10-4
