1. GPU Finite Element Method Computation Strategy Without Mesh Coloring
Abstract A GPU-adapted Finite Element Method (A-FEM) implementation without using a mesh coloring strategy to avoid race conditions is presented. All the elements are simultaneously processed, and the local data is computed and consolidated into the device memory in a new adapted Coordinate Format data structure (a-COO). The comparison between the proposed s

2. Interaction Analysis of Non-aligned Cracks Using Extended Finite Element Method
Abstract Multiple flaws are frequently occurred in actual components, such as pressure vessels and power plants. These flaws will in some circumstances lead to more severe effects than single flaw alone. Assessment of the interaction behavior is based on the evaluation of alignment and combination of these multiple flaws. In the current standards, multiple c

3. Mesh motion and surface remeshing / Movimento de malhas e remalhamento de malhas superficiais
Malhas dinâmicas são comumente utilizadas em problemas de simulação sobre dominios cuja geometria varia com o tempo. Sempre que o domínio onde a malha está definida é alterado, as molas são acionadas movimentando os vértices para que estes se conformem com a nova descrição do domínio. Os tipos de molas mais utilizadas são: as longitudinais, as t

4. A computational methodology for automatic two-dimensional anisotropic mesh generation and adaptation
This paper describes a versatile computational program for automatic two-dimensional mesh generation and remeshing adaptation of triangular, quadrilateral and mixed meshes. The system is flexible to be incorporated into an adaptive global or local remeshing procedure and for generating both, iso and anisotropic meshes. The main contribution of this work is t

5. A methodology and computational system for the simulation of fluid-structure interaction problem
In this paper a flexible finite element computational tool developed to investigate fluid-structure interaction applications in two dimensions is described. We consider problems which can be modelled as a viscous incompressible fluid flow and a rigid body-spring system interacting nonlinearly with each other. The coupling is dealt with the use of an interfac

6. Finite element-based model for crack propagation in polycrystalline materials
In this paper, we use an extended form of the finite element method to study failure in polycrystalline microstructures. Quasi-static crack propagation is conducted using the extended finite element method (X-FEM) and microstructures are simulated using a kinetic Monte Carlo Potts algorithm. In the X-FEM, the framework of partition of unity is used to enrich
