PROBLEM TO BE SOLVED: To provide a snow accretion simulation method excellent in reproducing a snow accretion phenomenon.SOLUTION: A snow accretion simulation method is the snow accretion simulation method for reproducing a snow accretion phenomenon, and includes: a step of calculating a velocity distribution of snow under situation where a solid object model 1 exists by calculation of a field of flow by a finite difference method; a step of calculating a sphere orbital using a result of the velocity distribution with scattering snow as a sphere 2; a step of a snow accretion determination of snow particles 3 moved by the sphere orbital by a particle method with the snow as particles; and a step of updating an external shape of the solid object model based on a result of being formed as accretion particles 4 by the snow accretion determination. Further, processing is repeated from a step of performing the calculation of the field of flow against the solid object model after updating.SELECTED DRAWING: Figure 1
