Does NX Convergent Modeling have

a Future in ShipBuilding?

NX Ship User Meeting, Sandvika, 08.06.2017

• Convergent modeling lets you work with Parasolid b-rep tools directly on faceted

geometry

• Convergent modeling eliminates the need for time consuming reverse engineering

processes

• The aim of this presentation is to introduce the concept and some simple use cases.

• We would also like to get the discussion and thought processes going in the group.

• We will not be making any conclusions – as this is a new technology and the first

introduction of convergent tools from Siemens

With NX11, Siemens launched a groundbreaking new technology that lets you work directly on faceted geometry

Does NX Convergent Modeling have a future in Ship Building?

Convergent Modeling: A short Background & Introduction

Norwegian Cruise Vessel “Crash landed”

Demonstration #1

The damage sustained by the cruise

vessel “Trollfjord” - the result of a

meeting with the dock in Risøyhamn - will

serve as our convergent use case.

Topics:

• Importing a convergent model

• Interacting with a convergent model

• Creating a Detail design plate

In this demonstration we will import an aft part of a

scanned hull. This will serve as the geometry we

want to limit the pod shape to.

Topics:

• Creation of parametric convergent geometry

• Detail Design Plates based on b-rep/facets

• Limitations in current version(?)

Creation of parametric b-rep geometry following the hull shape of scanned faceted geometry

Demonstration #2

• NX design can work with facets as any other geometry!

• Output from operations is facets (NX 11)

• Direct use of scan and polygon data without conversion

• No need for reverse engineering!

• History based modeling with facet geometry

• Booleans/Trims

• Associative wireframe

Business value

• Accelerate concept to production

workflows through increased use of

polygon/facet data
