The invention discloses a method and system for displaying a simulation result through fusion of finite element simulation and BIM. The method comprises the following steps that an obtained BIM model is analyzed; sending the analyzed component data to a finite element simulation model for simulation to obtain simulation model data; and according to simulation model data, modifying geometric coordinates and colors of the BIM model. According to the method, analysis processing and simulation are carried out on the BIM model, then geometric coordinates and colors of the BIM model are modified, the BIM model is deformed, coloring is carried out according to a response field, a finite element simulation and BIM fusion display simulation result is obtained, deep fusion with a business application scene can be achieved, waste of BIM model resources is not caused, and the method is suitable for popularization and application. Model deformation and response field visual expression based on the three-dimensional ...
