A multimesh adaptive scheme for air quality modeling with the finite element method

Abstract: Abstract. A multi-mesh adaptive scheme for convection-diffusion-reaction problems is presented. The proposal is applied to air quality modeling, especifically to the simulation of a pollutant punctual emissions. The performance of the proposal is analyzed with different nonlinear reaction models, including the photochemical model CB05 implmented within the Comunity Multiscale Air Quality model, which involves sixty-two species and very different characteristic reaction times. The problem is solved with splitti… Show more

“… Another relevant enhancement would be the introduction of the effect that the concentration of the ground-level ozone (O3), or tropospheric ozone, has over the transported NO2. Using a variable absorption term calculated from a chemical equilibrium equation could be a possibility (Monforte and Pérez-Foguet, 2014;Ghazali et al, 2010).…”

“…The most restrictive volume is the one used in the refinement. To chose the most demanding volume can lead to a very large mesh; to avoid this problem we will use a multimesh approach [Monforte and Pérez-Foguet, 2014b]. This scheme using a multimesh adaptation is described in Algorithm 6.1.…”

“…Adaptivity can lead to huge number of degrees of freedom when several species are considered. To handle this problem we propose to use a multimesh scheme where each pollutant specie is simulated in its own mesh [Monforte and Pérez-Foguet, 2014b]. Using this method, instead of having one mesh with a lot of degrees of freedom we have several meshes with a reasonable number of degrees of freedom.…”
