Description
  • V práci je prezentován a testován empirický algoritmus adaptace sítě pro dynamické modelování prostorově jednorozměrných reakčně-transportních systémů s počátečně separovanými složkami a pohyblivými gradienty. Studovaným systémem je tzv. elektrolytická dioda popsaná čtyřmi parabolickými hmotnostními bilancemi a jednou rovnicí eliptickou - Poissonovou rovnicí elektrostatiky. Dynamika formování otevřeného a zavřeného módu elektrolytické diody je studována a je popsána volt-ampérová charakteristika. Testování ukázalo, že navržený algoritmus může být použit pro studium dynamického chování řady systémů s pohybujícími se a extrémně strmými gradienty. (cs)
  • We present results of testing an empirical algorithm of mesh adaptation for modeling of spatially one-dimensional reaction-transport systems with initially separated components and large moving gradients. The algorithm combines newly developed procedures of r-refinement and standard FEMLAB procedures. The developed method uses an expansion of a dense mesh in neighborhoods of localized large gradients and estimates the mesh adaptation interval (based on the evaluation of transport times). The size of the neighborhood is dynamically controlled. The adaptation method has been tested on systems of parabolic-elliptic PDEs with extremely large moving gradients of concentrations and electric potential. We have found that CPU time requirements are comparable to other mesh adaptation solvers. The simplicity of the empirical procedure of the mesh adaptation and its easy implementation in standard dynamic solvers represent main advantages of the proposed method. The studied system, called an %22electrolyte
