A Non-uniform Staggered Cartesian Grid approach for Lattice-Boltzmann method
(2015-12-31)
We propose a numerical approach based on the Lattice-Boltzmann method (LBM) for dealing with mesh refinement of Non-uniform Staggered Cartesian Grid. We explain, in detail, the strategy for mapping LBM over such geometries. ...
LBM-HPC - An open-source tool for fluid simulations. Case study: Unified parallel C (UPC-PGAS)
(2015-12-31)
The main motivation of this work is the evaluation of the Unified Parallel C (UPC) model, for Boltzmann-fluid simulations. UPC is one of the current models in the so-called Partitioned Global Address Space paradigm. This ...

Offshore floating platforms for wind turbines represent challenging concepts for designers trying to combine an optimal compromise between cost effectiveness and performance. Modelling of the hydrodynamic behaviour of the ...
Towards a parameter-free method for high Reynolds number turbulent flow simulation based on adaptive finite element approximation
Hoffman, J.; Jansson, J.; Jansson, N.; de Abreu, R.V. (2015-05-01)
; Jansson, J.; Jansson, N.; de Abreu, R.V. (2015-05-01)
This article is a review of our work towards a parameter-free method for simulation of turbulent flow at high Reynolds numbers. In a series of papers we have developed a model for turbulent flow in the form of weak solutions ...
