Abstract: General Ray (GR) method for solution of the Dirichlet boundary
value problems for the Laplace type equation with variable coefficient is
proposed. The method is based on reduction of Partial Differential Equation
(PDE) to assemblage of Ordinary Differential Equations (ODE) using local
traces for considered functions and operators. GR-method presents the
solution of the Dirichlet boundary value problem for this type of equations
by explicit analytical formulas that use the direct and inverse Radon
transform. Proposed version of GR-method is justified theoretically,
realized as stable algorithms and program package in MATLAB system. The
quality of constructed software is demonstrated by numerical experiments.
Applications to the stationary problems of electrodynamics and HEAT TRANSFER
thermo conductivity are discussed.
