| summary |
The acoustic computational simulation presents many advantages but at the same time there are some limits corresponding, among others, to the modelisation of the hall geometry. The integrated modelers of geometry of the halls in the acoustic simulation software are based especially on the programming code modelisation via text editors of coordinate points and not on the graphical modelisation, as the CAD software is. In cases of complex architectural shapes of halls, the majority of the acoustic simulation software imperatively needs to import a model from a CAD software.
However, the modelisation of the geometry of the hall must take into account several criteria in order to run in an acoustic simulation software, and optimize the calculation results, such as the plane surfaces, the limited number of surfaces in some cases, the elimination of the unnecessary elements, the accepted geometry model format, etc.
This paper explains the description and the particularities of three different modelisation processes of the Architectural School Amphitheater of Bordeaux in a CAD system in order to be adequate for acoustic simulation via acoustic software, such as ASCII, dxf and normals orientation model formats. It also presents computer automatization aspects of these processes integrated in a plate-form adaptable to a CAD system named “CAD-Acoustic.” These modelisation processes can also be a helpful tool during the architectural conception of the acoustic hall. |
