Introduction There is a revolution going on, impacting and transforming how computational mechanics and the associated design and optimization are done: the emergence, availability, and large-scale use of OpenFOAM [1]. It belongs to the contemporary open-source trend not unlike the roles played by the Linux operating system or the Internet encyclopedia Wikipedia. OpenFOAM is free and is used by...

A general multigrid framework is discussed for obtaining textbook e ciency to solutions of the compressible Euler and Navier Stokes equations in conservation law form The general methodology relies on a distributed relaxation procedure to reduce errors in regular smoothly varying ow regions separate and distinct treatments for each of the factors elliptic and or hyperbolic are used to attain op...

We discuss some issues that arise in the implementation of numerical algorithms for computational fluid dynamics (CFD) on multiprocessor systems such as hypercubes. We identify several important kernel numerical algorithms from CFD that map well onto the hypercube architecture. We emphasize the importance of considering the optimal mapping for a collection of kernel algorithms used in an applic...

Computational Fluid Dynamics (CFD) simulations are aimed to reconstruct the reality of fluid motion and behaviour as accurately as possible, to better understand the natural phenomena under specified conditions. Ideally, computational models would need to cover different scales and geometric configurations, and the classic CFD solvers most often require long computational times to satisfy the c...

In a Priority Program on Massively Parallel Computing, eight Dutch research groups (http://www.phys.uu.nl/~mpr/) cooperate since 1995 to develop new algorithms and software to simulate the non-linear dynamics of thermonuclear, geo-physical, and astrophysical plasmas. As one result of this collaboration, the general-purpose Versatile Advection Codemonstrated excellent scaling properties across a...

Due to high applicability of the fixed bed catalytic naphtha reforming reactors, hydrodynamic features of this kind of reactors with radial flow pattern are improved in this work by utilising computational fluid dynamics technique. Effects of catalytic bed porosity, inlet flow rate and flow regime through the bed on the flow distribution within the system are investigated.It is found that t...
