  • Aiming at the problem that terrain data accuracy is not high in CFD grid generation, a grid generation method based on point cloud data complex terrain CFD was put forward.This method generates the local coordinates of the point cloud file through the introduction of a seven-parameter solution method,and by the point-line-face-volume method for mesh generation, further polyhedral mesh conversion,the terrain mesh is optimized.The example validation showed that the application of method can generate high accuracy data and consistent with the actual terrain mesh,is suitable for the later stage of the fine CFD simulation applications.
