A waterwave simulation method and apparatus, an electronic device, and a storage medium are provided. The method includes: in response to detecting that waterwaves need to be acquired during simulation on an initial model, acquiring one or more target regions corresponding to the waterwaves and one or more slots (11) corresponding to the one or more target regions; and obtaining a target model by attaching the one or more slots to the initial model, where an effect of waterwaves (12) is present in the one or more target regions of the target model. In the method, the target model can involve waterwaves by attaching the one or more slots with waterwaves to the initial model, and it is only necessary to allocate an internal memory and a display memory for the one or more slots without adding extra internal memory and display memory, which is beneficial to improve simulation efficiency.
