Continuous adjoint converge issue in transonic airfoil shape design
Hello everyone !
I am dealing with shape design problem and I have got some questions about adjoint parameters, thus I have troubles with converge adjoint calculations. My direct case was converged well.
To the flow solution I use RANS solver with SA turbulence model, Mach number is 0.85 and Re= 4.6e6. Direct calculation converged well with CLF number = 50, FGMRES linear solver with LU_SGS preconditioner, entropy fix coefficient = 0.5, second order flow equation and first order turbulence equation. I attach config file, mesh, screenshots, solutions and restart solution files in link below. I got stuck on this problem for several weeks and would appreciate if someone could help me. https://github.com/zloty001/CRM_ShapeDesign Regards, zloty |
