The ability to extend this API to accommodate 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<\/em>.<\/p>\n\n\n\n J. Belanger, Elligno Inc. Technical report no.

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.<\/em><\/p>\n\n\n\n \u00ab\u00a0A Test Field Calibration to Validate Shallow-Water Codes: the Case of the Ste- Marguerite River with AquaDyn\u00a0\u00bb<\/strong>, –<\/strong>J. Belanger , M. Carreau and A. Vincent, CERCA Technical Report no. R2000-6, (September 2000)<\/p>\n\n\n\n Abstract<\/strong><\/p>\n\n\n\n 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, <\/em>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 <\/em>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 <\/em>reproduce the observed flow regime with a deviation of less than a few percent locally.<\/em><\/p>\n\n\n\n\u201cScientific Projects in Industrial Applications<\/em><\/strong>\u201d, CD-Adapco (Lebanon, NH, USA) September 2008<\/strong><\/h5>\n\n\n\n
