Modelling of capillary water absorption in sound and cracked concrete using a dual-lattice approach: Computational aspects

Lattice models have been used to simulate mass transport to predict durability of cementitious materials. In particular, the use of dual lattice meshes allows for the coupling of fracture and transport processes, which commonly occur at the same time in these materials. Literature has shown good agreement between simulations and experimental...

Implementation of the BiCGSTAB method for the Helmholtz Equation on a Maxeler Data Flow Machine

To get a clear picture of the earth crust the Helmholtz equation needs to be<br/>solved and a high wave number is needed in order to provide fine grain details.<br/>The Stabilised BiConjugate Gradient method needs to be implemented to solve<br/>the Helmholtz equation. This is done on a Maxeler data flow machine to improve<br/>calculation times....

Preconditioning a Finite Element Solver of the Exterior Helmholtz Equation

We consider acoustic scattering about a general body. This is described by the Helmholtz equation exterior to the body. In order to truncate the infinite domain we use the BGT absorbing boundary condition. The resultant problem in a finite domain is solved by a finite element procedure. This yields a large sparse system of linear equations which...
