Technical substructure

Technical Overview

The FRIENDSHIP-Framework is a unique Computer Aided Engineering (CAE) system. It integrates geometric modeling, numerical simulation, systematic variation and formal optimization in the design of maritime products and turbomachinery. Core functionality may well be considered the parametric modeling approach. It allows you to model functional surfaces like ship hull forms and their appendages, propellers, turbines, compressors, pumps, volutes and similar casings, diffusers, stirrers—virtually all surfaces, which perform in a flow regime. For an optimal and efficient performance their quality has to be optimal. This is where the FRIENDSHIP-Framework is the functional tool for excellent results.

The FRIENDSHIP-Framework is a flexible integration environment for simulation driven design. The software facilitates a holistic design process by closely coupling Computer Aided Design (CAD) and Computational Fluid Dynamics (CFD). It bridges the traditional gap between CAD and CFD through a range of integration solutions. Designed as a flexible work environment, the software system is easily custimized.

The technical substructure is complex. In a nutshell, it provides:

• Extended Feature technology, e.g. scopes in Feature definitions, Feature definition editor, file I/O, launching of external processes and programs
• Components library
• Quality assessment for surfaces and curves
• Graphical User Interface features like workspaces, space mouse support, context menu in three views
• 2D graphics view with PDF export
• Automatic PDF diagram creation from design results
• Comprehensive integrated documentation
• Convenient project management
• Extensive optimization technology
  • single objective (Brent, Nelder-Mead Simplex, Tangent Search, Newton-Raphson)
  • multi objective (NSGA-II Genetic Algorithm, Multi-objective Simulated Annealing)

Details are listed in our data sheet Technical Overview.
