Hi, you can select the option "Response Surface Optimization in the Optimization workspace. Afterwards, you can check the option "Use Result Pool" It will ask you to select the pools which you want to utilize for the surrogate based optimization after starting the design engine. Please note that if you do not have sufficient samples in your result pool, it will do additional samples before starting the optimization. It will then perform the optimization on the surrogate in the background without calling CFD. After that, a new design will show up in CAESES, which is then evaluated using the CFD to check if it matches the prediction from the surrogate.

Hi Furkan, If you set up a "Response Surface Optimization" and choose to "use result pool", a surroate will be created (if your pool is large enough, otherwise samples will be added first). An optimization on that surrogate is performed automatically in the background (a Genetic Algorithm is used here) and the optimal candidate (or multiple if you choose so for a multi-objective problem) is returned. The design you see created in CAESES is therefore either an additional sample or already the potential optimum. Check the dakota.out file in your design directory to see the details. Also, the finaldata file will show you the predicted performance of the optimum... If you keep this Algorithm running, the actual (CFD) result(s) of the optimum-candidate(s) will be added to the pool for the next iteration and the process repeats. Cheers, Heinrich
