نویسندگان
چکیده
In this paper, the so-called “back and forth error compensation correction (BFECC)” methodology is utilized to improve solvers developed for advection equation. Strict obedience “discrete maximum principle” enforced by incorporating a gradient-based limiter into BFECC algorithm. The accuracy of algorithm in capturing steep-fronts hyperbolic scalar-transport problems improved introducing controlled anti-diffusivity. This achieved at cost performing an additional backward sub-solution-step modifying formulation accordingly. performance proposed assessed solving series benchmarks utilizing different combinations algorithms underlying numerical schemes. Results are presented both structured unstructured meshes.

DAMAGE IDENTIFICATION OF TRUSSES BY FINITE ELEMENT MODEL UPDATING USING AN ENHANCED LEVENBERG-MARQUARDT ALGORITHM
This paper presents an efficient method for updating the structural finite element model. Model updating is performed through minimizing the difference of recorded acceleration of real damaged structure and hypothetical damaged structure, by updating physical parameters in each phase using iterative process of Levenberg-Marquardt algorithm. This algorithm is based on sensitivity analysis and pr...
متن کاملMultiscale finite element for problems with highly oscillatory coefficients
In this paper, we study a multiscale finite element method for solving a class of elliptic problems with finite number of well separated scales. The method is designed to efficiently capture the large scale behavior of the solution without resolving all small scale features. This is accomplished by constructing the multiscale finite element base functions that are adaptive to the local property...
متن کاملAn Enhanced Finite Element method for Two Dimensional Linear Viscoelasticity using Complex Fourier Elements
In this paper, the finite element analysis of two-dimensional linear viscoelastic problems is performed using quadrilateral complex Fourier elements and, the results are compared with those obtained by quadrilateral classic Lagrange elements. Complex Fourier shape functions contain a shape parameter which is a constant unknown parameter adopted to enhance approximation’s accuracy. Since the iso...
متن کاملA Boundary Functional for the Least-Squares Finite- Element Solution of Neutron Transport Problems
The least-squares finite-element framework for the neutron transport equation is based on the minimization of a least-squares functional applied to the properly scaled neutron transport equation. This approach is extended by incorporating the boundary conditions into the leastsquares functional. The proof of the V-ellipticity and continuity of the new functional leads to bounds of the discretiz...
متن کاملFinite element models for the solution of underwater acoustics problems
Acoustic waves are used in SONAR systems for the detection and classification of objects which may be swimming in the water column, proud on the seafloor, or buried below the sediment. In some applications, such as low frequency detection and classification of structurally complex objects immersed in a fluid, signal processing techniques must be aided by a-priori model based knowledge of the ta...
