在偏微分方程的数值计算方法中,通常可分为网格化 (Mesh) 方法和无网格 (Meshfree) 方法两种。网格化方法发展较早,包括我们常用的有限差分 (Finite Different)、有限元 (Finite Element) 和有限体积 (Finite Volume) 方法。这些方法都强烈依赖于对计算区域的网格离散,常用的包括三角剖分、矩形剖分或泰森 (Thiessen) ...
Finite Element Method is used in calculation engine as it is also visible in the name of program (Finite Element Method = FEM). This chapter introduces the main concepts, features and functions of the built-in finite element method.
FINITE ELEMENT MESH GENERATING METHODPURPOSE: To generate a hexahedron mesh scarcely having a distortion against an arbitrary shape by dividing a tetrahedron element into four hexahedron elements and forming it as the hexahedron mesh of a non-structure grid of the whole model to be analyzed. ;...

3.1 Finite Elements The basic idea of the finite element method (e.g., Zienkiewicz and Taylor 1989) is to subdivide the actual material in small pieces, the finite elements, and to cast the behavior of these individual elements in a relatively simple algebraic form. When all the elements are...

ViennaMesh Meshing Finite element method Uniform programming interface 1. Introduction The finite element method (FEM) has proven to be efficient for solving boundary value problems and thus has become very popular in various fields of scientific computing. The FEM requires the simulation domain, commo...
The ALE/Lagrangian Particle Finite Element Method: A new approach to computation of free-surface flows and fluid–object interactions The Particle Finite Element Method (PFEM) is a well established numerical method [Aubry R, Idelsohn SR, Oate E, Particle finite element method in fluid mec... ...
Implicit methods such as Finite Element Method (FEM) or Implicit Surface Collisions (ISC) are often used for physics-based deformation. This technique is computationally expensive but provides more realistic and dynamic deformations. 5. Blendshapes: Blendshapes, also known as morph targets, involve ...
