AMR WRR paper 2020 - model

This repository contains information about the model that is used in our ########### paper.
The current version of the model simulates steady state unconfined groundwater flow. It is based on the finite element method using quadrilateral or hexahedral finite elements for the domain discretization. For the mesh generation we use adaptive mesh refinement where we start from a coarse mesh and refine the areas of the domain where there is rapid change in the hydraulic head.
In addition the water table elevation is treated as an additional unknown and the iterations of the unconfined non linear problem are blended with the iterations of the adaptive mesh refinement process.

本数据集仓库收录了我们用于一篇已作遮挡处理的论文的模型相关信息。该模型的当前版本可模拟稳态非承压地下水渗流，基于有限元法，采用四边形或六面体有限单元对计算区域进行离散化。网格生成环节采用自适应网格加密技术，即从粗网格出发，对测压水头变化剧烈的计算区域进行网格加密。此外，将地下水位高程作为额外待求量，将非承压非线性问题的迭代过程与自适应网格加密的迭代过程进行融合。
