A computer program for simulating convergent-beam electron diffraction patterns from single crystals and bicrystals is described. The program is based on the dynamical theory of electron diffraction, and the intensity of a convergent-beam disc is constructed from the individual intensities of a number of plane waves incident on the specimen. For the bicrystal case, this program allows the influence of parameters such as the location of the boundary plane and a rigid translation at the boundary to be investigated. These effects are discussed for a horizontal (111) twin boundary in silicon.
