摘要：A novel mesh generation algorithm is introduced for addressing 2D and 3D interface problems. The grid is constructed from an underlying quasi-uniform unfitted mesh, incorporating anisotropic triangles and quadrilateral elements in 2D, and anisotropic tetrahedral, pyramidal, and prism elements in 3D. Various types of low-order finite elements are presented, including H^1-conforming, H^1-nonconforming, and H(div)-conforming elements. We rigorously establish the optimal approximation capabilities of these anisotropic elements. Numerical experiments are conducted to validate the theoretical results.
