Porovnání 2D a 3D modelu dávkovače zinku
Mach, M. ; Musil, Ladislav
The paper deals with the mathematical and computer modelling of electromagnetic zinc feeder, which is a device for exact dosing of molten zinc. 2D and 3D models of the feeder were developed, solved and the results were compared and discussed. Computations were carried out by the professional FEM-based codes FEMLAB, OPERA, QuickField and a number of single-purpose user procedures written by the authors

Posuvný indukční ohřev a související jevy v kvazi-sdružené formulaci
Karban, P. ; Ulrych, B. ; Doležel, Ivo
The paper deals with quasi-coupled numerical solution of the problem of induction heating and associated phenomena in 2D axisymmetric arrangements. The process of heating is modeled by a special algorithm respecting the temperature dependencies of various material properties and (when necessary) time variable boundary conditions. The algorithm fully developed by the authors is illustrated on an example of continual induction hardening
