Many of the static and dynamic properties of dipolar Bose-Einstein condensates are can be studied from the Gross-Pitaevskii equation, a nonlinear nonlocal (integro-differential) partial differential equation. Here we develop a combined split-step Crank-Nicolson and fast Fourier transform based numerical scheme for both stationary and non-stationary solutions of the time-dependent Gross-Pitaevskii equation describing the properties of dipolar Bose-Einstein condensates at ultra low temperatures. We present results from the numerical scheme for energy, chemical potential, root-mean-square sizes and density of the dipolar BECs and compare them with results of other authors.
