Study on Twining of Virtual Seaweed in Fluid Environment
This paper describes the twining of seaweed in fluid environment by computer simulation of virtual seaweed. The morphology of virtual seaweed is modeled by Lindenmayer system. Then, two physical properties, which are adhesiveness and tear, are artificially introduced into this model. Physics engine is adopted to realize its physical motion. A fluid environment is constructed by the Lattice Boltzmann method. The method calculates time evolution of particle distribution to simulate fluid motion. The motion of virtual seaweed is acquired by moving in the environment. In order to find the twining conditions and the way of avoiding it, the simulation is executed by altering the environment. We ascertained that the virtual seaweed behavior has the close relationship with the water flow.
