Zusammenfassung:A lattice Boltzmann method (LBM)-based fluid analysis simulation device includes: an input unit which receives data on an analysis object for fluid analysis simulation; a grid generation unit which generates a grid system for calculating flow data based on input data; a node removal unit which removes some nodes among a plurality of nodes included in the grid system; and a flow data calculation unit which calculates flow data regarding the analysis object based on the grid system from which some nodes have been removed. LBM(Lattice Boltzmann Method) 기반의 유체 해석 시뮬레이션 장치에 있어서, 유체 해석 시뮬레이션을 위하여 해석 대상에 관한 데이터를 입력받는 입력부; 상기 입력받은 데이터에 기초하여 유동 데이터의 계산을 위한 격자계를 생성하는 격자 생성부; 상기 격자계에 포함되는 복수의 노드 중 일부 노드를 제거하는 노드 제거부; 및 상기 일부 노드가 제거된 격자계에 기초하여 상기 해석 대상에 관한 유동 데이터를 계산하는 유동 데이터 계산부를 포함한다.
