Paper Abstract:	Cultivation of marine plants is remarkable in the field of energy development. Physical simulation on computer is convenient for the analysis of the motion of marine plant populations. This is a practical approach in terms of cost in order to design the optimal cultivation system, device and environment. Our study aims to elucidate physics phenomenon in a large cultivation system of marine plants and provide new engineering insights into cultural techniques. This paper describes how to model the physical motion of marine plant populations which is cultivated under the high volume fraction. It is possible to consider the physical interference by representing the plant with rigid bodies and using physics engine. Our proposed modeling method keeps filling plant models while avoiding overlaps between the models in an interior of three-dimensional mesh structure object in order to reduce the error of physics calculation when handling many rigid bodies. A fluid environment is constructed by Lattice Boltzmann method in the virtual space. The dynamics of marine plant is approximated by applying buoyancy and drag force. Results show that the plant populations moves with fluid velocity while causing the adhesion between individuals.
