报告摘要:In this talk, I will talk about the multiphysics finite element methods for the some poroelasticity models. To reveal the multi-physical processes, the original model is reformulated into a fluid coupled problem. Then, a fully discrete finite element method based on the multiphysics reformulation is prpoposed. The stability analysis of the above proposed method and the optimal convergence order estimate are given, and some numerical examples are shown to verify the theoretical results. Finally, I introduce an adaptive PINNs for 2D and 3D poroelasticity models.
