Parallel simulation of variably saturated flow with adaptive mesh refinement (D08)

如果在整个域中不均匀地使用最高分辨率，而是在具有强变化性的区域中自适应地使用最高分辨率，则可以极大地加速3D地下水流的精确数值模拟。 我们将扩展新的并行原型代码的自适应混合有限元与预处理的非线性解决和时间依赖的情况下。新的并行自适应网格细化的并行算法，然后将被耦合到TerrSysMP ParFlow的地下组件。

The accurate numerical simulation of 3D subsurface flow can be accelerated tremendously if the highest resolution is not used uniformly throughout the domain, but adaptively in regions that feature strong variability. We will extend the new parallel prototype code for adaptive mixed finite elements with a preconditioned nonlinear solve and for the time-dependent case. New parallel algorithms for parallel adaptive mesh refinement will then be coupled to the subsurface component of TerrSysMP ParFlow.
