Algorithm for Adaptive Mesh Redistribution in Lattice Boltzmann Simulations
The Lattice Boltzmann method (LBM) is the alternative approach for hydrodynamic
equation solving. Two factors make it a favorite approach nowadays. Firstly, the attractive feature
of LBM is that it is intrinsic for parallel simulations due to the linear structure of the algorithm.
Secondly, what makes LBM special for the research, it is well applicable to the simulations in
complicated geometrical domains. The realization of the potential scalability relies on many factors.
We concentrate on one of the problems that may obscure synchronization of computing nodes simulating
problems that require redistribution of the adaptive mesh nodes between computing nodes
during the simulations process. We discuss how the recently proposed algorithm for redistributing
tasks in the population annealing can be modified in the LBM simulations with dynamical mesh
