Numerical Verification for the Asian Rust Dispersion in Paraná
Palavras-chave:
Asian rust, Discretization error, Richardson estimatorResumo
This work aims to study the discretization error of a numerical model describing the atmospheric
transport of the Asian Rust spores in Parana. The model was obtained from the discretization of a two-dimensional ́
Partial Differential Equation with diffusive, convective, and reactive terms by the finite difference method. To study
the behavior of the discretization error, a priori and a posteriori analyzes were performed. From the verification
process, it was found that the apparent order converged to the asymptotic order. Thus, the process of estimating
numerical errors through the Richardson Estimate presented promising results.
