An important aspect of atomistic simulations of dislocations is the construction of the initial dislocation configurations. However, limited configurations can be constructed by previous methods, impeding the simulations of a general dislocation configuration in real materials. In this paper, we develop a simple and general method for constructing dislocations with arbitrary shapes specified by the users, realising the Volterra process at the atomic level. Examples of its applications to a dislocation helix, the partial dislocations, the multi-dislocation configurations, and the dislocations in the imperfect crystal are presented, showing the capacity and robustness of the present method.
