Mr. Stefan Pietsch__0001 0 Report post Posted September 2, 2014 Hey, I am trying to remodel a bulbous bow so that I can use it for potential flow analysis. I have used a lofted surface to get one element for the complete bow. Afterwards I have used an image surface as basis for the transformation and the panelmesh. for the original shape it works well. But when I change the length and height parameters than the panelmesh crashes. I wonder if there is a better opportunity to create one surface for the whole bulbous bow? Cheers, Stefanexamplebow.fdbc Share this post Link to post Share on other sites
Mr. Claus Abt 14 Report post Posted September 3, 2014 HI Stefan,There seems to be a slight numerical problem with the length of the shift function and the lofted surface. If you add 1e-5 to the x-position of the points defining the forward end, it works nicely. CheersClaus Share this post Link to post Share on other sites
Mr. Stefan Pietsch__0001 0 Report post Posted September 3, 2014 Hey Claus, thank you very much. There are no problems with the transformation anymore! Cheers, Stefan Share this post Link to post Share on other sites
Matthias Maasch 21 Report post Posted October 4, 2014 Hi Stefan, I had a look into your attached project and I thought it is a nice example to show how to use the Analysis-Feature for Bulbous-Bow-Imports which you can find here. I created a surface group from your Surfaces-Import and passed it to the Analysis-Feature. Then I remodeled the function curves and used them as input for Curve Engines and finally I created Metasurfaces. Thus, your import is a fully parametric model in just a few steps. All you have to do now is to create some parameters for the main dimensions of the bulbous bow. exampleBowAnalysis.fdb Cheers Matthias Share this post Link to post Share on other sites
