A VEM–based mesh–adaptive strategy for potential problems
International Journal of Analytical, Experimental and Finite Element Analysis (IJAEFEA)(2019)
摘要
The Virtual Element Method (VEM) is an evolution of the mimetic finite difference method which overcomes many limitations affecting classic Finite Element Methods (FEM). VEM for 2D problems allows for exploiting meshes consisting of any polygonal elements. No limitations on their internal angles are needed. Hanging nodes are easily treated. Notably, VEM is well apt to meshâadaptive algorithms. In this paper we detail an implementation of meshâadaptive VEM for potential problems. We suggest a fresh, promising approach. We show on suitable test problems that a gain in efficiency can be obtained, respect to uniform, fine discretizations.
