In this paper, we propose a new triangular finite element mesh generation method based on simplification of high-density mesh and adaptive Level-of-Detail (LOD) methods for efficient CAE. Mesh simplification evaluating mesh properties is applied to control the mesh properties required for FE mesh, such as the number of triangular elements, element shape quality and size while keeping the specified approximation tolerance. Adaptive LOD methods based on vertex hierarchy according to curvature and region of interest, and global LOD method preserving density distributions are also proposed in order to construct a more appropriate FE mesh. these methods enable efficient generation of FE meshes with appropriate properties for analysis from a high-density mesh. Finally, the effectiveness of our approach is shown through evaluations of the FE meshes for practical use.

this paper proposes a fast approach to generate length-preserved natural boundary for intrinsic parameterization. Given a triangular mesh with disk-like topology, we compute an optimal boundary for its parameterization. An optimal boundary is expected to be length-preserved withthe length of every triangular edge on the boundary is invariant before and after parameterization;also, the boundary is requested to be natural where the inner angle is close to the angle excess at every boundary vertex on the given mesh. Computation of a length-preserved natural boundary is formulated as a constrained non-linear optimization problem, the procedure of solving which is in general very time-consuming. Here, we speed tip the optimization by adopting the scheme of sequential linearly constrained programming. It is shown at the end of this paper that our length-preserved natural boundary could greatly improve the speed and quality of the original intrinsic parameterization.

the concept of product view and the corresponding required models is a basic constituent of a product development process where shape transformations are repeatedly encountered. Here, topological and geometric issues are identified and major shape modeling principles are studied. As a result, some core concepts of a framework for product view integration are proposed and justified. Notions of mixed shape representation and layered topological representation are briefly outlined as part of the proposed framework. Categories of operators enabling the required shape transformations are also shortly introduced as element of the proposed framework.
