Finite Element Time-Dependent AnalysisIn Part 1 of this course, we discussed the applicability of frequency-domain and time-dependent analyses. Let's recap the circumstances that require a transient model:The excitation is a short pulse or includes more than one frequency component. The problem ...
A new technique for the numerical simulation of 3D time-dependent flow of viscoelastic fluid is presented. The technique is based on a Lagrangian kinematic description of the fluid flow and represents a further development of the 2D Lagrangian integral method (LIM). The convergence of the method ...

In this paper, we consider solving the coupled systems of discrete equations which arise from implicit time stepping procedures for the time dependent Stokes equations using a mixed finite element spatial discretization. At each time step, a two by two block system corresponding to a perturbed Stoke...
A finite element scheme is devised for the solution of nonlinear time-dependent exterior wave problems. The two-dimensional nonlinear scalar (Klein–Gordon) wave equation is taken as a model to illustrate the method. The governing equation is first discretized in time, leading to a time-stepping...

A general and powerful method of finding numerical solutions of dynamic time-dependent problems in mechanics is based on the reduction to ordinary differential equations of the partial differential equations describing the problem. This reduction can be effected by means of finite-element or finite-diff...
