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,

 

Stefan

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.

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.
