We introduce a new algorithm for generating tetrahedral meshes that conform to physical boundaries in volumetric domains consisting of multiple materials. The proposed method allows for an arbitrary number of materials, produces high-quality tetrahedral meshes with upper and lower bounds on dihedral angles, and guarantees geometric fidelity. Moreover, the method is combinatoric so its implementation enables rapid mesh construction. These meshes are structured in a way that also allows grading, in order to reduce element counts in regions of homogeneity.
我们介绍了一种新算法，用于生成符合由多种材料组成的体积域中物理边界的四面体网格。所提出的方法允许任意数量的材料，生成具有二面角上下界的高质量四面体网格，并保证几何保真度。此外，该方法是组合式的，因此其实现能够实现快速网格构建。这些网格的结构方式还允许进行分级，以减少均匀区域中的单元数量。
