Finite element mesh generation method and device based on arch dam simulation and storage medium

The invention relates to the technical field of water conservancy and hydropower engineering, in particular to a finite element mesh generation method and device based on arch dam simulation and a storage medium. Comprising the steps of obtaining a three-dimensional model, partition parameters and a preset grid size of the arch dam; dividing the three-dimensional model into a plurality of partitions according to the partition parameters to obtain a three-dimensional partition model; on the basis of the principle that the surface grid densities of the partitions corresponding to the upstream surface and the downstream surface are consistent and can be mapped, a two-dimensional grid is constructed according to the contour features, the multiple partitions and a preset grid size; mapping the two-dimensional grids on the upstream surface and the downstream surface of the three-dimensional partition model according to each partition to obtain a dam body three-dimensional grid; according to the contour features, a
