Data for: unstructured Voronoi grids for MODFLOW

The data contains two data sets of underground water flow problems using MOFLOW 6. The first one is the classical Darcy problem, simulated with a nested Locally Refined Grid (LGR) and using a Voronoi grid. The second one is a simulation of a classic 2D quarter five-spot problem, using several kinds of LGR and Voronoi grids. Result visualization can be done using ParaView (*.vtu file are given) or using TOUGH2Viewer. LGR grids can be visualized using ModelMuse 4.0 or higher.
