Numerical simulation in Infinite precisions. New pre-condition methods. Analysis of numerical integrations. Mesoscopic simulation of concrete materials.
2. Applied and numerical analysis of nonlinear problems. Analysis of the system of phase separations. Error estimates using Hausdorff metric. Code of finite element methods for mandtle convections. Analysis of reaction-diffusion systems. Navier-Stokes equations with friction type boundary conditions. Numerical methods for free boundary problems. Analysis of Ginzburg-Landau equation.
3. Numerical simulations of several fluid dynamics. Two-phase flows. Navier-Stokes flows.
