TLDR
In this article, a three-dimensional finite element model for the pollutant dispersion is presented, where the first stage consists on the construction of an adaptive tetrahedral mesh of a rectangular region bounded in its lower part by the terrain and in its upper part by a horizontal plane.About:

On the modeling of atmospheric pollutant dispersion during a diurnal cycle: A finite element study
TL;DR: In this paper, the authors presented a numerical model to study pollutant dispersion in the atmospheric boundary layer (ABL) by accounting for the mechanisms of advection by the mean wind in the horizontal direction, turbulent diffusion in the vertical direction to ground surface, dry deposition, and radioactive decay.

Wind Forecasting Based on the HARMONIE Model and Adaptive Finite Elements
Albert Oliver,Eduardo Rodríguez,José María Escobar,Gustavo Montero,Mariano Hortal,Javier Calvo,J. M. Cascón,Rafael Montenegro +7 more
TL;DR: A new method for wind field forecasting over complex terrain using the predictions of the HARMONIE meso-scale model as the input data for an adaptive finite element mass-consistent wind model with a minimal user intervention.

Isogeometric Residual Minimization Method (iGRM) with direction splitting for non-stationary advection–diffusion problems
TL;DR: The method mixes the benefits resulting from isogeometric analysis, implicit dynamics, residual minimization, and alternating direction solver with direction splitting, and shows that the resulting system of linear equations has a Kronecker product structure, which results in a linear computational cost of the direct solver.

A multimesh adaptive scheme for air quality modeling with the finite element method
TL;DR: In this paper, a multimesh adaptive scheme for convection-diffusion-reaction problems for a large number of components is presented, where the evaluation of the nonreactive part for each component and the reaction at each node constitute independent tasks.

Finite element simulation of chimney emissions: a proposal for near field impact assessment in highly complex terrains
TL;DR: In this article, a strategy for three-dimensional finite element simulation of pollu- tion evolution in highly complex terrains is presented, which is useful for the impact assessability of punctual emissions in the near field, up to few tens of kilometres.
3-D Adaptive Wind Field Simulation Including Eects of Chimney Emissions
TL;DR: This paper presents a model for computing an initial velocity eld based on the contribution of the observed wind and the vertical buoyancy or momentum plume rise dened by a Gaussian plume model and develops a simultaneous untangling and smoothing procedure to optimise the resulting meshes.
