[0061] 1. Select the research terrain area, determine the calculation domain, and establish the calculation domain grid model under complex terrain according to the GIS elevation data;
[0062] 1.1 Select longitude 116.2° and latitude 39.8° as the origin coordinates of the bottom center of the target calculation domain, select a calculation domain model with a length, width and height of 800m, and obtain the terrain elevation DEM data file of the calculation domain from the GIS system;
[0063] 1.2 Use a meshing program to divide the computational domain into meshes. The number of meshes in each layer is equal and is a triangular mesh unit. Each unit is in the shape of an irregular triangular prism as a whole;
[0064] 1.3 Import the DEM data file to the server, and then use the self-programmed program to raise or lower the Z coordinate of the bottom grid of the already divided computational domain grid model according to the DEM data file, and interpolate to simulate the CFD m...
