Rull 0 Report post Posted February 3, 2021 Hi everyone, First of all, I would like to ask about why I did the same practice from ffd tutorial but it fail to do deformation of my bulb. Why this condition happen (as shown in picture) and anyone knew the way to solve this problem? Your help is highly appreciate for me, thank you. Share this post Link to post Share on other sites
Mr. Heinrich von Zadow 12 Report post Posted February 3, 2021 Hi Rull, I can not tell this from the picture alone. Did you set the FFD as a transformation (create and image surface from your existing bulb or assign it to a BRep if that's what you have). If you can't get it to work, feel free to attach your project here. Best regards, Heinrich Share this post Link to post Share on other sites

Mr. Heinrich von Zadow 12 Report post Posted February 8, 2021 Hi Rull, I looked at your project and it works just fine -- see attached animation. I guess there will be some tweaking of the spacing and transformations of the points to get some really good shapes, but technically, it works. Did you make sure you look at the image surfaces and not the initial ones? Cheers, Heinrich Share this post Link to post Share on other sites
Christina 0 Report post Posted June 5, 2021 Greetings Rull. I am a student doing my final year project. Currently I am looking for document/file for bulbous bow optimization using ffd method. Is it possible for me to get the model of the bulbous bow for me to practice my ffd? It would mean so much to me. Thank you in advance. Share this post Link to post Share on other sites
Mr. Heinrich von Zadow 12 Report post Posted June 9, 2021 Dear Christina, the file Rull has posted further up seems to be very similar (if not identical) to the sample we ship with CAESES5. Just search for it in the help workspace (bottom left corner of the GUI) and you should find this: Best regards, Heinrich Share this post Link to post Share on other sites

Mr. Heinrich von Zadow 12 Report post Posted September 23, 2022 Dear Aina, it seems that you have not selected any points for the 3 transformations that you have prepared. I attached a small demo of how that's done as well as the modified project.
