LUNDIsim : open-data multiresolution model meshes with porosity and permeability properties inspired from SPE10 challenge for geoscience and data science applications

This note describes the content of LUNDIsim dataset. It consists in five main meshes in GRDECL format: one common hexaedral (Corner Point Grid) mesh model, plus four meshes filled with permeability and porosity values, corresponding to distinct subsurface environments. The latter four meshes are provided with lower-resolution versions, meant for geoscience, reservoir engineering, and data science applications (rendering, simulation, upscaling, compression, learning).
