Development of a Finite Element Methodology for Flexible Track Models in Railway Dynamics Applications
The dynamic analysis of railway vehicles involves the construction of three independent models: the vehicle model; the track model; and the wheel-rail contact model. In this work, a multibody formulation with Cartesian coordinates is used to describe the kinematic structure of the rigid bodies and joints that constitute the vehicle model. A methodology is also proposed in order to create detail...
متن کاملJava Performance in Finite Element Computations
1 The performance of the developed Java finite element code is compared to that of the C finite element code on the solution of three-dimensional elasticity problems using Intel Pentium 4 computer. Untuned Java code is approximately two times slower then analogous C code. It is shown that code tuning with the use of blocking technique can provide Java/C performance ratio 90% for the LDU solutio...
متن کاملExplicit Finite Element Method Applied to Impact Biomechanics Problems
Biofidelic numerical models require accurate geometry, material properties, representative loading conditions, and proper verification and validation based on relevant experimental studies. Imaging techniques such as CT or MRI are typically used to generate anatomically correct model geometry. Accurate biological material properties and constitutive models present a challenge s...
متن کاملComparison of C and Java Performance in Finite Element Computations
The Java programming language has several features, which makes it attractive for software development in computational engineering and sciences. One major obstacle to use of Java in computationally intensive applications is its reputation of a slow language in comparison to Fortran or C. In this paper the performance of the developed Java finite element code is compared to that of the C code o...
متن کاملPerformance Boundaries for Interactive Finite Element Applications
This paper presents work characterizing finite element performance boundaries within which live, interactive finite element modeling is feasible on current and emerging systems. These results are based on wide-ranging tests performed using a prototype finite element program implemented specifically for this study, thereby enabling the unified investigation of numerous direct and iterative solve...
