Unstructured & Hybrid Grids Generation
Grid generation is commonly regarded as one of the most crucial and difficult tasks in the simulation of geologically complex problems.
I developed a new method to generate unstructured quadrilateral grids which are locally refined and highly orthogonal for irregular and complex geometries. And my research also covers the hybrid grids generation method to combine the advantages of both structured and unstructured grids. |
Discretization
The great potential of unstructured grids comes with many challenges including development of robust and efficient discretization schemes.
We studied on different discretization schemes for unstructured grids, and developed advanced unstructured grids-based discretization methods on the accuracy, robustness and efficiency of general-purpose numerical simulation. |
Multi-physical Fields in Porous Media
Accurate numerical modeling of flow and transport in porous media needs to take the coupled interactions between involved various physical fields into account.
We conducted coupled simulation of temperature, water and stress fields of porous media using finite volume method (FVM) and finite element method (FEM) for unstructured grids. |
