<p>Com o objetivo de quantificar o balanço hidrológico e compreender a dinâmica do fluxo das águas subterrâneas do Sistema Aquífero Urucuia (SAU), na bacia hidrogeológica do rio Corrente, realizou-se uma simulação do fluxo dessas águas, em regime permanente. O SAU aloja-se na bacia hidrográfica do São Francisco e é composto pelo conjunto de aquíferos interligados, cujo arcabouço é formado pelas rochas do Grupo Urucuia. O sistema é do tipo poroso granular, com geometria de um espesso tabuleiro, constituído essencialmente por arenitos. O método de elementos finitos foi utilizado na simulação numérica, empregando-se o algoritmo computacional FEFlow<em> (Finite Element Subsurface Flow e Transport Simulation System</em>). Por meio da simulação numérica foram estimados os parâmetros hidrodinâmicos: recarga máxima de 267 mm/a e mínima de 142 mm/a; condutividade hidráulica horizontal e vertical de 9,7 x 10<sup>-5</sup> m/s; fluxo de base de 1,26 x 10<sup>7</sup> m³/dia. Os resultados ressaltam a importância da bacia do rio Corrente na manutenção da vazão do rio São Francisco e confirmam a natureza homogênea e isotrópica do SAU.</p>

Since it is too complex to make the engine connecting rod design digital and too amount of work to make mistakes, a method based on the CATIA to achieve the engine connecting rod digital design is proposed. Firstly, the parameterized modeling of connecting rod is completed based on secondary development of CATIA. And then, the finite element analysis is applied to the model. Finally, the analysis results verify the effectiveness of the proposed method.

Rubber diaphragm forming is one of very important manufacture method in aircraft manufacturing. In order to achieve the purpose of precise forming and high efficient simulation of the rubber diaphragm forming for the aircraft sheet metal parts in CAE software of ABAQUS, first the blank design module is developed and embedded into ABAQUS in the use of one step inverse finite element method because there is no blank design algorithm in ABAQUS. Then according to the characteristics of the rubber diaphragm forming, development technology on ABAQUS is applied to develop a rubber diaphragm forming simulation system based on combining Graphical User Interface GUI and the scripting language of Python. In this system, the parameter definition plug-in and finite element modeling module are designed to save a lot of tedious steps, so the blank parameters and process parameters can be defined rapidly and the simulation process can be simplified in ABAQUS, which can greatly improve the analysis speed and improve the efficiency of the finite element method. Finally the accuracy and effectiveness of the rubber diaphragm forming simulation system are verified by the simulation of a typical part that is a door frame bracket of aircraft.

A method of simulating nanoimprint process dynamically is proposed and a software program has been made to complete the simulation process automatically. Finite element method (FEM) is used to reveal mechanism of how the liquid flow in the imprint process by every static state. By means of static model iteration,we make a software to simulate the flow process dynamically and it can be used to forecast the result of the nanoimprint. The simulation system is used to predict residual layer thickness in the waveguide fabrication process.

This paper does some research and discussion on the finite element analysis of a building structure, especially the computer graphics simulation method in building structure simulation. Moreover, with the support of BIM technology and computer finite element simulation technology, this paper constructs a building structure simulation system and analyzes the building structure simulation system based on actual conditions such as building structure and stress load. In addition, this paper improves the traditional structural analysis algorithm and designs experiments to evaluate the effect of the method proposed in this paper and analyze the data in the form of simulation to compare the validity of the test results. Finally, an experiment is designed to evaluate the data processing capability of the test system in this paper. The experimental analysis results verify the effectiveness of the method in this paper, which can provide relevant theoretical references for subsequent building structure simulation.
