Worst scenario method applied to heat conductivity structures formed by composite materials
Chleboun, Jan
Uncertain conductivity coefficients are considered. They are not given directly bat they stem from an admissible family of composite materials characterized by uncertain concentrations of their constituents. The goal is to maximize a weakly continuous **st functional and to suggest an approximate method suitable for numerical solution of the problem.

Numerical solution of initial-value problems for nonlinear parabolic equations by the finite element method becomes an essential tool for the development of new technologies in applications to electromagnetics, diffusion and heat transfer processes, chemistry, coupled problems, and others. The paper is concerned with the application of higher-order adaptive schemes.

According to the general framework of the method of lines, we split the numerical solution of the nonstationary compressible Euler equations in 1D, 2D and 3D into the three following steps: First, the system of PDE´s is semidiscretized in space. Second the smoothness and Lipschitz continuity of the right-hand-side (RHS) of the arising system of ordinary equations (ODE´s) is analyzed and its solvability is discussed. Third, classical ODE packages ( we use ODEPACK and DDASPK ) are applied to the system of ODE´s.
