Time-dependent problems with the boundary integral equation method

Time-dependent problems that are modeled by initial-boundary value problems for parabolic or hyperbolic partial differential equations can be treated with the boundary integral equation method. The ideal situation is when the right-hand side in the partial differential equation and the initial conditions vanish, the data are given only on the boundary of the domain, the equation has constant co...

Regularized integral formulation of mixed Dirichlet-Neumann problems

This paper presents a theoretical discussion as well as novel solution algorithms for problems of scattering on smooth two-dimensional domains under Zaremba boundary conditions—for which Dirichlet and Neumann conditions are specified on various portions of the domain boundary. The theoretical basis of the proposed numerical methods, which is provided for the first time in the present contributi...

Volume integral equation formulation for scattering using conformal finite elements

A method of moments solution of volume integral eqna,tions (VTEs) for scattering and radiation problems involving arbitrarily shaped inhomogeneous dielectric structures is presented. The inhomogeneous region is modeled using second order hexahedral elements whereas low order conformal basis functions within these elements are used for the method of moments expansion of the unknown. The resultin...

Finite Difference Solution of Mixed Boundary-value Elastic Problems

A new numerical method of solution has been developed for the analysis of deformation and stresses in elastic bodies subjected to mixed boundary-conditions. The program is capable of dealing with both regular and irregular shapes of boundaries appropriately. An ideal mathematical model, based on the displacement potential function, has been used in the finite difference solution. The present pa...

Integral Equation Formulations for Geodetic Mixed Boundary Value Problems

We consider mixed boundary value problems in Physical Geodesy and study possibilities in order to transform them into a system of integral equations over the boundary of the domain. The system of integral equations can be solved numerically, by, e.g. boundary element methods, provided that (a) the mixed boundary value problem is uniquely solvable, (b) the system of integral equations is equival...
