Abstract:In this talk, I will talk about themultiphysicsfinite element methods for the quasi-static thermo-poroelasticitymodel. To reveal the multi-physical processes of deformation, diffusion and heat transfer, the original model is reformulated into a fluid coupled problem. Then, a fully discrete finite element method based on the multiphysicsreformulation is proposed. 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 poroelasticitymodel.
