EN A special description of the boundary variation in a shape optimization problem is investigated. This, together with the use of a potential theory for the state, result in natural embedding of the problem in a Banach space. Therefore, standard differential calculus can be applied in order to prove t[...]

EN A meshless method for the solution of linear and non-linear Poisson-type problems involving high gradients is presented. The proposed method is based on collocation with 3rd order polynomial radial basis function coupled with the fundamental solution. The linear problem is solved by satisfying the b[...]

EN An initial stability of Kirchhoff plates is analysed in the paper. Proposed approach avoids Kirchhoff forces at the plate corner and equivalent shear forces at a plate boundary. Two unknown variables are considered at the boundary element node. The governing integral equations are derived using Bett[...]

EN The paper presents the method of fundamental solutions (MFS) for solving electromagnetic problems. We compare the MFS with the method of boundary integral equations in solution of potential problems. We demonstrate the MFS techniąue together with the Lapiace transform in application to the problem o[...]

EN The paper describes an approach to solving parabolic partial differential equations that generalizes the well-known parametrix method. The iteration technique proposed exhibits faster convergence than the classical parametrix approach. A solution is constructed on a manifold with the application of [...]

EN This paper presents numerical solution to a problem of the transient flow of gas within a two-dimensional porous medium. A method of fundamental solution for space variables and finite difference method for time variable are employed to obtain a solution of the non-linear partial differential equati[...]

PL Celem pracy jest konstrukcja macierzy rozwiązań podstawowych dla liniowego sprzężonego parabolicznego układu równań w przestrzeni trójwymiarowej zawierającego dwa równania. Macierz rozwiązań podstawowych skonstruowano używając transformacji Fouriera. Bazując na macierzy rozwiązań podstawowych przeds[...]
EN The aim of this paper is to construct the matrix of fundamental solutions for linear coupled parabolic system in the three-dilinensional space, consisting of two equations. The matrix of the fundamental solutions has been constructed using the Fourier transform. Basing of the matrix of fundamenal so[...]
