Advances in multi-domain lattice Boltzmann grid refinement
TL;DR: A decimation technique for the copy from the fine to the coarse grid based on a filtering operation is introduced and it is demonstrated that to reconstruct the information, a local cubic interpolation scheme is mandatory in order to get a precision compatible with the order of accuracy of the lattice Boltzmann method.

TL;DR: A inhomogeneous cellular automata model in which several species compete for their territory and can co-evolved in regions where several of them coexist is proposed.

Automatic grid refinement criterion for lattice Boltzmann method
TL;DR: A novel algorithm for the lattice Boltzmann method is proposed, based on physical concepts, to automatically construct a pattern of local refinement of the regular grids, and it is shown that the automatically refined grid can lead to results of equal quality with less grid points, thus sparing computational resources and time.

C. Cattoën,Jono Conway,Nava Fedaeff,Daniel Lagrava,Paula Blackett,Kelsey Montgomery,Ude Shankar,Trevor Carey-Smith,Stuart Moore,Andrea Mari,Tilmann Steinmetz,Samuel H. Dean +11 more
TL;DR: The Aotearoa (New Zealand) Flood Awareness System (AFAS) as mentioned in this paper uses a high-resolution convective-scale atmospheric model with statistical perturbations in rainfall, soil moisture and baseflow to generate a 50-member ensemble.
