Numerično računanje tridimenzionalnih problemov s permanentnimi magneti po metodi končnih elementov ob uporabi reduciranega skalarnega potenciala : doktorska disertacija
Tičar, Igor
Delo predstavlja prikaz izboljšav pri računanju statičnih magnetnih polj z metodo končnih elementov, ob uporabi reduciranega magnetnega skalarnega potenciala. Izkaže, se da se lahko izognemo ...računskim napakam v področju visoke parmeabilnosti z uporabo t.i."robovnih" elementov. Z njihovo pomočjo opišemo vrtični del magnetnega polja. Prikazane so metode za reševanje problemov stacionarnega magnetnega polja, vsebujoče predstavitev z robovnimi elementi. Posebej je nakazana možnost reševanja v primeru, ko je poznana tokovna porazdelitev. Podan je model permanenetnega magneta, ob predpostavki konstantne remanentne gostote, ter poznanih krivuljah magnetnega v direktni in prečni smeri. Dana sta dva tridimenzionalna problema, v prvem primeru s permanentnimi magneti, v drugem pa tudi z dodatnim vzbujanjem. Pokazana je primerjava med računalniško rešitvijo in med merjenimi vrednostmi.
