Numerical Simulation of Creature Flow by Using a Directional Molecular Potential and Motivation Function

Creatures, such as humans, fishes or birds move in a cluster or crowd almost always. The characteristics of crowd motion were discussed from the point of fluid dynamical view. The motivation of its motion was classified into 7 categories due to the intelectual level. In the present report, lowest three categories were taken into consideration. In order to express an individual molecular potential, a poly-nominal potential function was discussed and introduced for human model. Directional and influence functions in the dynamics of collision were introduced to take account for the dependency of view angle of creatures. Thermo-dynamical macro quantity such as temperature, pressure and density were defined for the creature flow. Simple models of collision of two individuals and of cross flow between two crowds were simulated by using the present technique.
