“…2 (2012) mesh and surface node-based pointers to define the nodes lying along the lines of off-surface structure in the mesh. Ierotheou et al (2000), reported also a flow solver (ESAUNA) for the compressible Navier-Stokes equations, that was able to utilize hybrid meshes. ESAUNA too, used a data structure that specially treated the block structured regions.…”

An unsteady incompressible numerical method for the solution of Navier-Stokes equations is presented. The finite volume solver adopts the method of artificial compressibility, using an implicit dual time stepping scheme for time accuracy. The 2D solver operates on general hybrid meshes containing triangles and quadrilaterals, while the 3D solver operates on hybrid meshes containing tetrahedra, pyramids, prisms and hexahedra. The developed algorithms for spatial discretization and time integration are mesh transparent. An upwind spatial discretization scheme is used for the convective terms and a central scheme for the diffusive terms. Efficient calculation of flow fluxes is implemented in an edge-wise fashion. A new combined method for efficient and accurate evaluation of variable gradients is achieved by using an averaging technique and by avoiding multiple spatial integration of the same element of the mesh. The results obtained agree well with numerical solutions obtained by other researchers.

“…This partitioning strategy is usually used for problems where data is static or the domain is unchanging but the computation within different parts of the domain is dynamic. In the majority of the research investigations on parallel CFD, this terminology of domain decomposition is referred to as grid partitioning ([20], [21], [22], [23], [24], [25]). Behind this term of grid partitioning lays a simple idea which came from a natural way of dealing with large-scale computational meshes.…”

This work is aimed to exploit the computational capabilities of nowadays workstations by building algorithms parallelized for a limited number of processors. For an engineer that is working in aerodynamic design, the possibility of having efficient and whenever available computational resources is a considerable advantage. By using adaptive algorithms to numerical solution conform to workstation's hardware configuration, acceptable processing time and enough accurate solutions configuration can be obtained. The algorithms were tested on different hardware platforms and encouraging results were obtained.
