报告摘要:In this talk, I will talk about the multiphysics finite element methods for poroelasticity and thermo-poroelasticity models. To reveal the multi-physical processes and to propose stable numerical methods, I will introduce the multiphysics approach, which reformulates the original model into a fluid coupled problem. Then, we propose a fully discrete finite element method based on the multiphysics approach to overcome locking phenomenon for both displacement and pressure. And we show the optimal convergence order estimate and some numerical examples to verify the theoretical results.
