TetrahedralMesh Editing with Local Feature Manipulations
Volumetric mesh models are widely used nowadays for product quality evaluation, physically-based deformation, numerical simulation, and so on. In the application of Computer Aided Design (CAD) and Computer Aided Engineering (CAE) integration, directly manipulating mesh models can reduce much during the simulation process. However, this integration is limitted or only provided from CAD to CAE nowadays. In this paper, we propose a framework for volumetric mesh editing based on feature dimensions. In our framework, the volumetric mesh is first decomposed into volumetric feature model based on corresponding surface features. Then, the random-walk based interpolation algorithm is applied to manipulate the local features. Our framework allows users to change the dimensions of the recognized features directly on the volumetric mesh. The optimizing operations, which is limited to local features, is applied to the tetrahedrons of the volumetric features once the quality of the elements does not meet the requirements. Experimental results show that the features hold precisely after the editing operations. Additionally, experimental data shows the quality of the elements keep well after editing the tetrahedral mesh.
