3D mixed boundary value problems: numerical algorithms, data structures and technologies of implementation

Technological aspects of the numerical solution to multi-dimensional boundary value problems (BVP) for partial differential equations (PDEs) using the finite difference, the finite element or the finite volume methods are described. Among them, the mathematical formulation of the problem, definitions of objects under consideration, algorithms of approximation with different accuracy orders, description of the code FVSDE3 and estimates of parallelization speedup.
