The granular materials phenomenon known as Brazil-nut effect is discussed in this work, where its grain configurations are constructed artificially as time-independent using 2-d disks. Single intruder with 2.6 cm diameter is introduced to granular bed consisted of 1.3 cm diameter disks. Each created configuration is designed similar to observed one in experiments and simulations. Potential energy and number of contact points between grains are observed between initial and final configurations. Contactopy parameter change is also discussed. As comparison results from real experiment and simulation are also presented.
