model a hull from scratch knowing the offsets

Recommended Posts

Hi Priyanka,

 

There is a tutorial section in the documentation browser of CAESES. I recommend to go through the most basic ones first, before you dive into ship hull modeling. There are a few concepts you need to learn and that are also important for ship hull design in CAESES (e.g. creating dependencies, 2D curves, parametric sweep surfaces / meta surfaces, parameters, design variables etc).

 

With this knowledge, you can then also start modeling a ship hull.

 

Hope this helps,

Joerg

Hi there,

 

What we have seen so far is that users e.g. 

 

  • Import their offset data to CAESES either through file > import > offsets or through custom features.
  • Create curves from these data sets
  • Analyze these curves and intersect at relevant locations to create deck curves, waterline curve, center plane curve etc.
  • Based on these new curves, start creating a surface model using lofted (skinning) surfaces or meta surfaces

Check out this set of features for hull modeling, in particular, the OffsetGroupBaseCurves.fdf which creates the deck curve, waterline etc. from offset data.

 

Maybe anyone else can give you an example, I'll check again.

 

Cheers

Joerg

Check the following:

 

  • Active filters right at the 3D view (buttons for point, curve, surface etc)
  • Active name filter at the 3D view
  • Your objects are not within the zoomed area
  • Visibility of the scopes in the object tree - maybe you clicked on a scope accidentally which sets it invisible
  • Visibility of objects in the object tree, the same as above

Hi Priyanka,

 

1) The input for the "Base Curve" within the Curve Engine, has to be in fact an attribute coming from the feature.

In your case, you are using the feature called "Aft Section" and you can find the available curves at the Drop Down List.

 

2) I can see that there are 7 errors, But from the console output it is possible to see only the last two. If you provide me a screen capture where I can see them all, I might be more helpful.

 

But most probably you forgot to define FOS or Beam as input argument.

Hi Priyanka,

 

As guessed the argument FOS is missing within the arguments list.

You can create a new argument named FOS of double type, which might solve the problem.

Hi Priyanka,

 

Please find the attached project.

 

changes made

an input argument of type Double for FOS

To the related Design Engine the base curve is assigned which is "section"

The coordinate system is changed to Y-(XZ)

 

And the project seems to be working.

 

Cheers

hi Ceyhan

 

yes I have offsets of a hullform and I want to develop or model that hull form using the offfsets and create its variants and finally see what will be the best hullform for a constant displacement.

 

Request if you could give some insight on this.

 

thanx!

 

cheers

Priyanka
