Parallelization technologies and grid data structures for solving three-dimensional boundary value problems in complex domains on quasistructured grids

When parallelizing the solution of three-dimensional boundary value problems, especially in domains with complex geometry, the сomputational technologies and data structureы are important. The amount of stored information and the computational time depend on them. In this paper we propose the technologies for parallelizing the method of decomposition of the computational domain into subdomains conjugated without overlapping on a quasistructured grid. Parallel grid data structures oriented mainly to work with structured data arrays are developed. An illustrative example clarifying the fundamentals of the proposed approach is discussed.
