چکیده
Thompson, Charles A. MSEE, Purdue University, May 1992. A Study of Numerical Intjegration Techniques for use in the Companion Circuit Mcthod of Tr,lnsicn~ Circuit Analysis. Major Professor: Gerald T. Heydt. Circuit transient analysis packages such as SPICE and EMTP are very widely used, but detailed information on the internal structure and error chal-acteristics for these software packages is lacking. Both SPICE and EMTP rely on numerical integration to approximate the transient response of circuit elements. 'The numerical integration methods used in the packages are not necessarily the most accurate ap~lroximations to the actual response of a circuit. The study of these numerical inkgration methods and their error characteristics is the focus of this thesis. Coinparisons are made between several methods in terms of accuracy and stability a s well as algorithm and time complexity involved with implementing tlhe integration me~hodolagies. CHAF'TER

A Rapidly Convergent Nonlinear Transfinite Element Procedure for Transient Thermoelastic Analysis of Temperature-Dependent Functionally Graded Cylinders
In the present paper, the nonlinear transfinite element procedure recently published by the author is improved by introducing an enhanced convergence criterion to significantly reduce the computational run-times. It is known that transformation techniques have been developed mainly for linear systems, only. Due to using a huge number of time steps, employing the conventional time integration me...
متن کاملP-stability, TF and VSDPL technique in Obrechkoff methods for the numerical solution of the Schrodinger equation
Many simulation algorithms (chemical reaction systems, differential systems arising from the modeling of transient behavior in the process industries and etc.) contain the numerical solution of systems of differential equations. For the efficient solution of the above mentioned problems, linear multistep methods or Runge-Kutta technique are used. For the simulation of chemical procedures the ra...
متن کاملStability of the Modified Euler Method for Nonlinear Dynamic Analysis of TLP
Efficiency of numerical methods is an important problem in dynamic nonlinear analyses. It is possible to use of numerical methods such as beta-Newmark in order to investigate the structural response behavior of the dynamic systems under random sea wave loads but because of necessity to analysis the offshore systems for extensive time to fatigue study it is important to use of simple stable meth...
متن کاملNumerical Simulation of a Lead-Acid Battery Discharge Process using a Developed Framework on Graphic Processing Units
In the present work, a framework is developed for implementation of finite difference schemes on Graphic Processing Units (GPU). The framework is developed using the CUDA language and C++ template meta-programming techniques. The framework is also applicable for other numerical methods which can be represented similar to finite difference schemes such as finite volume methods on structured grid...
متن کاملNonlinear Numerical Integration Scheme in Strain Space Plasticity
Strains are applied to the integration procedure in nonlinear increments todecrease the errors arising from the linearization of plastic equations. Two deformationvectors are used to achieve this. The first vector is based on the deformations obtained bythe first iteration of the equilibrium step, and the second is acquired from the sum of thesucceeding iterations. By applying these vectors and...
