CAFE

NAVAL ARCHITECTURE PROGRESS would like to introduce to you in collaboration with its partners AS2CON and BVB, the innovative rapid ship modelling and postprocessing tool CAFE.

cafe

NAP is the exclusive reseller of CAFE in Greece and Cyprus and has also right to resell worldwide. NAP has contributed with its 32 years experience in ship design to make CAFE an essential tool with customized functions for ship concept design and classification checks for ship structures.

CAFE is an innovative software for simple and rapid generation of ship concepts. The software relies on an easy-to-design logic which enables a user-friendly design enviČronment, 3D ship and equipment models can be imported into the system, CAFE autoČmatically generates classification drawings that include equipment arrangement. CAFE capabilities can be seen in the video at www.bvbcafe.com.

Ship modelling features

  • geometry can be imported from other CAD software
  • properties of plates along with realistic profiles are imported from MS Excel and can be expanded3 modified or replaced by user
  • enhanced and simplified man-model interaction utilizes arbitrary inclined guiding planes that add, reshape, move or split any entity in a 3D model
  • supported 3D surfaces include Chaikin' surface definition, B-spline and NURBS
  • elements attached to a guiding plane can change their shape and the number of attached beam elements
  • magnetic surface concept enables automatic surface reshaping to fit the shape of another neighbouring surface
  • internal structure along with the imported equipment can be visualized by walk-trough visualization capability
  • multi-user collaboration is supported in real-time
  • automatic generation of classification drawings at desired intersection planes and shell plating

Automatic Features

  • all structural element types can be automatically meshed and refined for the purpose of FEM or hydrodynamic analysis
  • calculation of volumes, masses and position of structural center of gravity
  • several types of structural loading area available, including wave loads utilized by Smith Correction
  • balancing the loads and reaction forces on boundary conditions in case when full ship FE model is being analyzed
  • FE models and hydrodynamic mesh can be transferred to external solver such as NASTRAN, FINNSAP and LS-DYNA
  • Hydrodynamic mesh can be easily exported for analysis
