A simulation model of concentrated colloidal rod-like nanoparticles is developed. As the governing equation of motion of a nanoparticle, the Langevine equation with external force is used. The external force includes capillary force, contact force, electrostatic force, van der Waals force, and elastic force which occurs inside an elastic rod. Numerical simulations are performed for the system of concentrated colloidal rod-like nanoparticles, which experiences solvent evaporation with a constant rate. Consequently, some structures of self-organized rod-like nanoparticles are obtained for the specified aspect ratios. The time evolution of the system is quantitatively analyzed by using the orientational order parameter and the non-dimensional boundary area. Moreover the two quantities are found to resolve the structures obtained in the simulation.
