An explicit, adaptive, hybrid finite element/finite difference method is proposed for the numerical solution of Maxwell’s equations in the time domain. The method is hybrid in the sense that different numerical methods, finite elements and finite differences, are used in different parts of the computational domain. Thus, we combine the flexibility of finite elements with the efficiency of finit...

steel shear walls, like bracings are a resistance system against wind and earthquake loads, which have more advantages than other systems. this paper is investigating the influence of openings on steel shear walls under increasing static loads. for this purpose, the experiments of other researchers on finite elements method have been checked and after investigating the correctness and precision...

This paper describes an algorithm to extract adaptive and quality 3D meshes directly from volumetric imaging data. The extracted tetrahedral and hexahedral meshes are extensively used in the Finite Element Method (FEM). A top-down octree subdivision coupled with the dual contouring method is used to rapidly extract adaptive 3D finite element meshes with correct topology from volumetric imaging ...
