Susan 0 Report post Posted November 13, 2023 Hi,anyone here,I want to do a full parametric modeling of the bow,it's an icebreaker bow ,but i don't know how to do it. I hope someone can help me. Sincerely !!! Susan Share this post Link to post Share on other sites
Mr. Heinrich von Zadow 9 Report post Posted November 13, 2023 Hi Susan, do you have something to start with (an existing CAD file, hull lines, etc.)? Share this post Link to post Share on other sites

Mr. Heinrich von Zadow 9 Report post Posted November 13, 2023 That sounds like a good start. I'd start importing it and look into partially parametric modelling techniques. BRep morphing, Free Form Deformations, Delta Shifts all work well in different areas of hull design. If you have specific questions regarding particular shape variations, feel free to ask. A lot also depends on constraints and the objective of your optimization problem. Share this post Link to post Share on other sites

Yes, I have tried to do a BRep morphing by FFD to the bow ,but it changed too little.So I try to rebuild the bow of the ship. Share this post Link to post Share on other sites

Mr. Heinrich von Zadow 9 Report post Posted November 13, 2023 There is plenty of material. Have you had a look into the documentation? Share this post Link to post Share on other sites

Unfortunately, I don't have any materials and can only rely on the help documents in the software,and I do not find some material about full parametric modeling.

Mr. Heinrich von Zadow 9 Report post Posted November 14, 2023 Hi Susan, I'd recommedn to start with these: (they are part of any CAESES installation) Share this post Link to post Share on other sites

I wonder if you have advice. Thankfully!!! I used the future below. And result is as follows. Share this post Link to post Share on other sites
Mr. Heinrich von Zadow 9 Report post Posted November 17, 2023 Hi Susan, If you use this method "smooth joint to stem" for the selected surface in your screen shot you will have to make sure the adjacent surface is defined such that it results in the same shape along the joint edge (possibly you will also want continuity accross the edge -- that would be another thing to keep in mind). What about you trim the upper surface and extend the lower one all the way to the max height? BTW: Which version of CAESES are you working with? Looks like a 4.x to me. I definitely recommend to update to the latest 5.2.4 -- there is years of development in between them. Cheers, Heinrich Share this post Link to post Share on other sites
