COVID Resources. Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated resource results are available from this ’s WebJunction has pulled together information and resources to assist library staff as they consider how to handle coronavirus. This series of volumes on the "Frontiers of Computational Fluid Dynamics" was introduced to honour contributors who have made a major impact on the field. The first volume was published in and was dedicated to Professor Antony Jameson; the second was published in and was dedicated to Professor Earl Murman.

These proceedings of a well-established conference on numerical methods, calculations, and modelling in fluid dynamics concentrates on five topics: multidimensional upwinding, turbulent flows, domain decomposition methods, unstructured grids, and flow visualization, and it includes papers presented at a workshop on all-vertex schemes.

and propeller-hull interaction. While most applications of the algorithm have been to generic hull forms such as the Wigley hull and to research forms such as the Ser accurate simulation of the flow around these hulls suggest that it is capable of general application and represents a good starting point for complex forms such as combatants with transom sterns and bulbous bows.

Multi-Block Grids The implementation of implicit multigrid methods on multi-block grids seems relatively straightforward, but there are a number of strategic choices that must be made, and it is important to assess the effects of these upon the performance of the algorithm.

Yadlin. All multigrid computations presented herein use W-cycles with one iteration of the non-linear solver before the restriction, and one iteration after the prolongation, sometime referred to as W(1, 1). Closure for the RANS equations is supplied by the Spalart–Allmaras turbulence model, solved on the fine-grid level only, decoupled from the mean Cited by: Cai et al.

tried to examine the use of multigrid for an explicit flow solver using traditional overset approach but as its implementation is not straightforward, only grid sequencing is used whereby coarse grids computations are first made before transfer to finer and finer by: Multi-block Structured Grids with Application to Aerodynamic and Hydrodynamic Configurations* S.P.

An implementation of the discrete adjoint approach for optimization of general three-dimensional unsteady turbulent flows on single-block unstructured grids is described in Refs. 3 and 5. The paper considers the parallel implementation of an algebraic multigrid method.

The sequential version is well suited to solve linear systems arising from the discretization of scalar elliptic PDEs.
