Présentation de l’environnement de programmation que nous développons pour la modélisation physique des écoulements à ciel ouvert, cas du bris de barrage. J’ai parlé de l’architecture de type framework, notre processus de développement basé sur une approche moderne qui utilise plusieurs pratiques empruntés au monde industriel.

An Extensible C++ Framework for One-Dimensional Open Channel Flow Simulation

Abstract

In this report we provide an introduction to ODE, then present an extensible Object-Oriented framework – written in C++ – with emphasis on the reusability of modules for ODE solvers. The ability to extend this API to accomodate new algorithms as they are developed is particularly attractive. This facilitates our work to find the best numerical method, and speed the development of a dedicated simulator for specific cases.

A C++ Differential Equations Solver using Object-Oriented Numeric“,

J. Belanger Elligno Inc. Technical Report no. TR-2006-01 (September 2006)

Abstract

Over the last few years we have been migrating a small library of numerical code originally written in C to C++. In this report, we present the mathematical abstractions used and how object-oriented programming techniques are applied for scientific software design. Finally implementations details are provided including relationship between data structure. The result is tight, readable code that is easy to maintain and extend. Example with Shallow water equations is drawn from our prototype C++ based environment.

 

A Test Field Calibration to Validate Shallow-Water Codes: the Case of the Ste- Marguerite River with AquaDyn“,

J. Belanger , M. Carreau and A. Vincent, CERCA Technical Report no. R2000-6, (September 2000)

Abstract

This paper reports on a rigourous field testing of AquaDyn for a rapidly varied shallow water flow in a complex river geometry. AquaDyn, a Surface Water Modeling Software, uses a finite element code to solve numerically the  Saint-Venant equations. The river reach selected for the field test is a 2 km section of the Sainte-Marguerite river located in the province of Quebec. This river reach was chosen for the complexity of its river flow and for the quality of the field data available. The reproduction of  the observed hydraulic flow of the Sainte-Marguerite river reach is a strong validation for shallow-water codes. The reach exhibits torrential flow, transition to fluvial condition through an hydraulic jump, complex bed elevation including an island and flood planes. In this report, we demonstrate that AquaDyn numerical results successfully reproduce the observed flow regime with a deviation of less than a few percent locally.

    Tips and Tricks!

    Le langage C++ offre de nombreuses caractéristiques qui le rende bien adapte pour la programmation scientifique. En particulier la surcharge des opérateurs, permet d'écrire du code qui modélise les types mathématiques de manière naturel. Je présente une class C++ de notre environnement de programmation qui met en évidence cette caractéristique
