In the present study, we modified the simulation method for calculating the trapped field distribution of large bulk Nd-Ba-Cu-O superconductors by taking account of B dependence of Jc. First we modeled the Jc-B property of Nd-Ba-Cu-O with the secondary peak effect by assuming that the sample has two different Jc components: one for normal B dependence and the other with the peak effect. Based on the Jc-B results thus determined, we could obtain the trapped field distribution of large grain Nd-Ba-Cu-O, which was in good agreement with the empirical data.
