Shape idealization transformations are very common operations when adapting a CAD component to FEA requirements. Here, an idealization approach is proposed that is based on generative shape processes used to decompose an initial B-Rep solid, i.e., extrusion processes with material addition are used to segment a solid. The corresponding extrusion primitives(More)
Extraction of generative processes from B-Rep shapes and application to idealization transformations. HAL is a multidisciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or(More)
Digital Mock-ups (DMUs) are widespread and form a common basis for product description. However, DMUs produced by industrial CAD systems essentially contain geometric models and their exploitation often requires new input data to derive various simulation models. In this work, analysis and reasoning approaches are developed to automatically enrich DMUs with(More)
Currenlty, FE meshes form the basic representation for the analysis and visualization of 3D FE analysis results. In this case, the triangulations used for visualization purposes are colored in accordance with the values issued from the resolution phase. As FE models get larger (hundreds of thousands and over), their 3D visualization become more and more(More)
