Coupling the Worst Scenario Method with Fuzzy Input Data
Chleboun, Jan
2003 - English
Inputs entering a mathematical model are considered uncertain, i.e., they are not given in a crisp form but only within a set of admissible data. The solution to the model is evaluated through a functional (criterion) reflecting a particular feature of the solution, e.g., local temperature, velocity, stress. The higher value, the "worse" solution. The goal of the worst scenario method...

Applications of the Method of Lines to Flow Problems
Segeth, Karel; Šolín, P.
2003 - English
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. Podle obecného schématu metody přímek rozložíme numerické řešení nestacionárních stlačitelných Eulerových rovnic v 1D, 2D a 3D na následující tři kroky. Především semidiskretizujeme soustavu parciálních diferenciálních rovnic v prostoru. Za druhé, analyzujeme hladkost a lipschitzovskost pravé strany vzniklé soustavy obyčejných diferenciálních rovnic a diskutujeme její řešitelnost. Nakonec použijeme standardní software pro řešení obyčejných diferenciálních rovnic ( speciálně soubory ODEPACK nebo DDASPK ).
