An Exponentially Fitted Finite Element Scheme for Diffusion Process Simulation on Coarse Grids

  • S. Mijalković
Conference paper


A new finite element scheme for diffusion process simulation, which allows coarse grid spacings in the areas of exponentially varying concentrations and fluxes, is proposed. It employs a nonlinear test function obtained from local divergence free conditions. Two-dimensional test computations show clear superiority of the exponentially fitted finite element scheme over the standard approach, as well as its robustness regarding irregular grid geometry.
