    Abstract: PURPOSE: An efficient time numerical analysis method of a 2D convection diffusion model for gas concentration is provided to limit a calculation area as a part of the whole area, thereby rapidly and accurately calculating the gas concentration. CONSTITUTION: A value applied to a variable used for a dioxide formula of a 2D convection diffusion model is inputted and initialized(S100). A convection environment is set up(S200). A calculation area in a gas concentration is expanded to the amount of expansion(S300). A numeric analysis calculation is performed for the expanded available area(S400). The available area is reduced corresponding to a calculation result(S500).
