Osman 0 Report post Posted August 21, 2022 Hi Everyone, I am working on a nose cone as you can see in the image and I am using the free form deformation method. I control the nose cone with 4 different sections and I have assigned the scale ratio to be used for each section as a different design variable. So there are a total of 4 design variables(r1,r2,r3,r4). Consecutive design variable values should not be less than each other. For example, if r1 is 0.2, the lower bound of r2 should be 0.2. But I can't control it. Any ideas on how to do it? Thank you, Best Regards Osman Share this post Link to post Share on other sites
Mr. Heinrich von Zadow 9 Report post Posted September 5, 2022 Hi Osman, you can use a parameters to define the bounds and design variables to scale in-between. See attached example. Cheers, Heinrich parameterScaling.cdb Share this post Link to post Share on other sites
