thank you for your attention. I saw some of them and I am learning now. but I don't have much time and I need a Guarantee (not learning) to know I am not wasting my time on this software. If you used it, please help me. I just want to know about CAESESE's ability to complex geometry generation, multiple objective optimization, not failing geometry during the optimization and integration with meshing and CFD tools. That is new and my master does not trust me to use it!
