Abstract
A lattice Boltzmann method (LBM)-based fluid analysis simulation device according to an embodiment of the present invention comprises: an input unit for receiving data pertaining to an analysis target for fluid analysis simulation; a grid generation unit for generating a plurality of calculation grid systems for calculating flow data on the basis of the received data; and a flow data calculation unit for calculating the flow data pertaining to the analysis target on the basis of a flow equation in the plurality of calculation grid systems. The plurality of calculation grid systems include: a fixed grid system generated to be stationary in a space of the analysis target; and a rotating grid system having an overlapping area overlapping the fixed grid system and generated to rotate in the space of the analysis target.
