Modeling and Assessing Nailing Conduct Utilizing FEM Method

Two-Level Hierarchical FEM Method for Modeling Passive Microwave Devices

In recent years multigrid methods have been proven to be very e cient for solving large systems of linear equations resulting from the discretization of positive de nite di erential equations by either the nite di erence method or the h-version of the nite element method. In this paper an iterative method of the multiple level type is proposed for solving systems of algebraic equations which ar...

A Combined BEM/FEM Method for IC Substrate Modeling

Investigating Stabilized Excavations Using Soil Nailing Method in Urban Context

There are various methods for stabilizing excavations in urban areas which one of them is the nailing method. Designing a nailing system and analyzing the performance of excavations is done by various software applications. One of these computer programs is PAXIS software which run based on the finite element method (FEM). In the present study, a numerical analysis of the performance of t...

Optimized linear FEM for modeling deformable objects

The main contribution of our work is a technique to accelerate the real-time simulation of deformable objects using a stable finite element method. Our purpose is to construct a preconditioner matrix for the coefficient matrix of the implicit integration scheme based on the global rotation matrix of the object. We describe some required steps to compute an optimal preconditioner in an off-line ...

Responsive FEM for Aiding Interactive Geometric Modeling

Numerical simulation methods are used mainly as off-line verification tools in current computer-aided engineering systems to reject designs that fail to satisfy the required constraints, rather than to guide the user toward a better design. This paper presents the integration of a real-time finite-element method (FEM) analysis into interactive geometric modeling. Real-time feedback from numeric...
