... consistency and traceability from the requirements to the further design stages. The theoretical formalization of our approach presents a consistent integration of geometry knowledge all along the conceptual design. Then, the corresponding modeling platform implementation between the developed system modeling...

... geometry complexity and need to be performed at each time step, making the simulation run very slow. In this paper, we address the problem of physics preserving model simplification for real-time potential flow based simulator for a USSV in the time domain, with an arbitrary hull geometry.

..., and the resolution and accuracy of the specific application. This is a critical problem because, normally, the object shape is assumed as a combination of different geometries with different morphological complexities. As a consequence of this, while some basic geometries (i.e., planes, cylinders, and cones) require...

Variance-covariance matrices of substitute geometry’s parameters for inspection of the first error model. Results are obtained from 100...

.... Then a basis of defects is built with the natural modes. A defect is projected in this basis and thus the coordinates (modal coefficient) represent it. Hence, tolerancing is possible, by limiting those coordinates. The methods proposed in the literature can be applied on elementary geometries...

.... DSM, described in the previous section, uses only the geometry of the feature’s influence center and boundary to determine its parameterization, and the shape of a basis function to determine the shape of the feature. DSM is used primarily to add bumps or indentations to a surface. The boundary...

We combine the revealed capabilities of multiresolution control with the ability of linear constraints to prescribe precise freeform geometry, all in the framework of interactive editing of nonuniform B-spline curves. Our implementation as well as all the examples...
