vecuws

The finite element calculations are performed by a descendant of vecu, which has been adapted for the solution of the stochastic Landau-Lifshitz equation (cf. section ). Like the finite difference program it consists of three main parts.

An initialization part, in which the preprocessing data are read and the VECFEM subroutines are prepared for the calculations. Then, there is the time step loop. The implementation of the time integration is described in the following section. After each time step, all interesting quantities are calculated and stored in log files. The magnetization distribution is saved for postprocessing with the visualization program AVS.
