Fast Finite Element Method Using Multi-Step Mesh Process
This paper introduces a new method for accelerating current sluggish FEM and improving memory demand in FEM problems with high node resolution or bulky structures. Like most of the numerical methods, FEM results to a matrix equation which normally has huge dimension. Breaking the main matrix equation into several smaller size matrices, the solving procedure can be accelerated. For implementing ...
متن کاملFinite element mesh generation and adaptive meshing
This review paper gives a detailed account of the development of mesh generation techniques on planar regions, over curved surfaces and within volumes for the past years. Emphasis will be on the generation of the unstructured meshes for purpose of complex industrial applications and adaptive refinement finite element analysis. Over planar domains and on curved surfaces, triangular and quadrilat...
متن کاملSize Functions and Mesh Generation for High-Quality Adaptive Remeshing
We present a new method for remeshing of triangular and tetrahedral meshes. Relative element sizes are computed from an error estimation. Then their gradient is limited in an optimal way by solving a Hamilton-Jacobi equation numerically. The new mesh is generated using smoothing-based iterations with connectivity updates (changes in topology of the mesh). The boundary nodes are projected using ...

متن کاملAdaptive Remeshing Method via Inversion of Element Anisotropy in Large Deformation Finite Element Analysis
The large deformation finite element analysis such as metal forming analysis usually involves processes to deform, stamp, or punch a part drastically, which causes great changes in shape of the part during the simulation. As the part is reshaped, the mesh elements are deformed, and element shape quality is decaying as analysis continues. To resolve this problem, it is common to adaptively remes...
