hpVersion of the Finite Element Method in Boundary Layer Problems
The performance of hp-version of the finite element method in the case of boundary layer problems of convection-diffusion type is presented. The method is also considered in the case of...

Structural Response Statistics by Boundary Elements
In this paper a boundary element method for problems of random vibration of continuous structures is presented. The method reduces the effect of the mesh size on the accuracy of the results....

Boundary Element Calculation of Nonlinear Wave Generation and Wave Current Interactions
A boundary element model is used to simulate the problem of nonlinear wave generation, and the interactions of wave and current. The numerical model is established based on the potential...

Chaotic Advection in a Shear Layer
The developing (in time) inviscid shear layer, although not yet in its turbulent regime, displays all the characteristics of chaotic advection. The corresponding Lyapunov exponent is strictly...

Time-Domain Transmitting Boundary Condition in Fluid-Structure Interaction Studies
One of the major difficulties in the nonlinear analyses of fluid-structure interactions has been the lack of exact expressions for the transmitting boundary in the time domain. Researchers...
