Solutions to micromagnetic standard problem No. 2 are presented in this article and the main features of the computational techniques used are discussed. Values of coercivity and remanence have been obtained in the range 0.8<d/lex<20.0. A continuous transition from uniform to nonuniform rotation is observed leading to a steady decrease in the coercivity as the ratio between the scaled geometry and the exchange length is increased. A sharp transition in the remanent states is found at d/lex=9.0. The nonuniform reversal mechanism is discussed and is found to consist on transitions between in-plane S-shaped patterns. The results are interpreted qualitatively.
