In order to match the growth of the decentered square and the evolution of the interface cell in a two-dimensional cellular automaton-finite volume method (CA-FVM) model with decentered square algorithm, the present work first alters the determination of the half length of the square diagonal according to the preferential growth orientation, and then modifies the interface evolution considering...

A recent emergence of the Finite Volume Method (FVM) in structural analysis promises a viable alternative to the well-established Finite Element solvers. In this paper the linear stress analysis problem is discretised using the practices usually associated with FVM in uid ows. These include the second-order accurate discreti-sation on Control Volumes of arbitrary polyhedral shape; segregated so...

Cloud computing visualize as the next generation computing technique for Information technology due to advantages provided by this technology. Cloud computing solutions are scalable, advanced and low cost. Its nature is distributed as cloud, it is indefensible to a large category of attacks are very frequent. Security is major challenge in cloud computing . This paper proposed the creation of F...

The multigrid method used with OpenMP/MPI hybrid parallel programming models is expected to play an important role in large-scale scientific computing on post-peta/exa-scale supercomputer systems. In the present work, the effect of sparse matrix storage formats on the performance of parallel geometric multigrid solvers was evaluated, and a new data structure for the Ellpack-Itpack (ELL) format ...

In various water transmission systems such as long-distance transfer projects and hydropower stations, accurate simulation of hammer is extremely important for safe stable operation the realization intelligent operations. Previous calculations usually consider only steady-state friction, underestimating decay transient pressure. A second-order Finite Volume Method (FVM) considering effect unste...

Computational fluid dynamics (CFD) applies numerical methods to solve transport phenomena problems. These include, for example, problems related flow comprising the Navier–Stokes equations either compressible or incompressible fluids, together with turbulence models and continuity single multi-component (reacting inert) systems. The design space is first segmented into discrete volume elements ...
