An adaptive coupled level-set/volume-of-fluid interface capturing method for unstructured triangular grids

We present an adaptive coupled level-set/volume-of-fluid (ACLSVOF) method for interfacial flow simulations on unstructured triangular grids. At each time step, we evolve both the level set function and the volume fraction. The level set function is evolved by solving the level set advection equation using a discontinuous Galerkin finite element method. The volume fraction advection is performed...

An Agglomeration Multigrid Method for Unstructured Grids

A new agglomeration multigrid method is proposed in this paper for general unstructured grids. By a proper local agglomeration of finite elements, a nested sequence of finite dimensional subspaces are obtained by taking appropriate linear combinations of the basis functions from previous level of space. Our algorithm seems to be able to solve, for example, the Poisson equation discretized on an...

We study how the underlying graph of dependencies of one dimensional cellular automaton may be used in order to move and compose areas of computations. This allows us to deene complex cellular automata, relaxing in some way the inherent synchronism of such networks. and asynchronous computations.

An Agglomerated Multigrid Method on Unstructured Hybrid Grids for Turbulent Compressible Flow

A multigrid accelerated Navier–Stokes solver, utilizing mesh agglomeration on hybrid meshes is described. The governing equations are discretized by a finite volume approach where stabilisation and discontinuity capturing is achieved by the use of a JST flux function on each edge. The method is an attempt to reduce computational cost of viscous calculations on unstructured meshes and some examp...
