Optimization of time step and finite elements on the model of diffusion of chlorides
Original language description
The paper deals with model of a reinforced concrete bridge deck loaded with effects of deicing agents. The theoretical 2D example is focused on the optimization of the mesh of finite elements and assessment of size of time stepping. The model uses finite element method based on thermal-diffusion analogy. The algorithm is implemented in Matlab. The original algorithm that is enhanced by optimization criteria is used to evaluate the results. They are compared with an analytic equation for time dependent chloride penetration including the effect of aging. Thus obtained results allow speeding up further calculations.
