Gas film cooling simulation split grid division method and system

The invention relates to the technical field of model grid processing, and provides an air film cooling simulation split grid division method and system, and the method comprises the steps: importing a model, segmenting the imported model into a plurality of independent domains, converting a sub-model entity corresponding to each domain into a sheet body set, and carrying out the classification and grouping of sheet bodies in the sheet body set; generating two-dimensional grids on the surfaces of the grouped sheet bodies according to a grid division rule, and performing quality inspection on the two-dimensional grids on the surfaces of the sheet bodies; mapping the two-dimensional grid passing the quality inspection on the surface of the sheet body into a boundary layer entity grid, generating a three-dimensional grid according to the boundary layer entity grid, and performing quality inspection on the generated three-dimensional grid; and positioning and placing the three-dimensional entity grid passing the
