Architecture and construction principles for Computational Fluid Dynamics software for engineering in industry

For flow simulation around (parts of) aerospace vehicles, aerospace industry needs CFD software. For users in industry, not only the functionality of the software is relevant. Timely availability and cost of the first version and later versions are other relevant factors. These factors are represented in the software characteristics timeliness,...

A survey of the NARSIM C/S middleware

This document describes the Client/Server system architecture of NARSIM - the NLR Air Traffic control Research Simulator- focussing on the socalled middleware: the infrastructure that enables all the seperate parts of the simulator to interact with each other. To show the full scope of the architecture, first a somewhat abstract architecture...

DEFMEF predesign document

The predesign document of DEFMEF presents the decisive requirements for the DEFMEF language and the associated DEFMEF translator. It also shows a basic technical design, which fulfills the requirements. DEFMEF as a software design language has been designed so, that it is possible to describe both a technical design and a detailed design with it...

Predesign for flow visualizer. Project: Flow Graphics, Work package: Visualizer for 3D flow-calculation results

The results of calculations of two- and three-dimensional flows on blocked grid domains consist of vast data collections with a simple, regular structure. The inspection of these results can only be done efficiently by graphical means, and by exploiting the regular structure of the data. There is a large similarity between the format of the...

Voorontwerp methodenbestandssysteem - Preliminary design method base system

The informatics policy at NLR is focussed on providing an infrastructure for the development of information systems. A new component in the infrastructure is the method base system, designed to support the management and use of algorithm implemented in programs. The preliminary design analyses the functions of the method base system and...

A system for the numerical simulation of sub- and transonic viscous attached flows around wing-body configurations

A description will be presented of a computer program system that is being used for the prediction of aircraft steady aerodynamic characteristics. Properties of the system are described from two different viewpoints. One is that of the aerodynamic designer, who needs an information system to predict lift, moment and drag characteristics and to...
