The theory of infinite tube magnetization reversal, formulated by Lee and Chang, has been reconsidered. For this purpose, a standard micromagnetic simulation package OOMMF was used. To account for elongated geometry of ferromagnetic nanotubes grown nowadays, an extension module has been written allowing application of periodic boundary conditions in one dimension. The results of the modelling exhibit a basic agreement with the theory. Limitations of the approach have been described and checkpoints have been discussed necessary in finite difference simulations performed for such structures.
