B.6.1 Cartesian to Unstructured output In order to simplify the reading of the dataset into existing tools, the Cartesian data was converted into a fully unstructured VTK mesh made of hexahedra. Solution data at cell centers of the hexahedra are averaged to cell corners accounting for block neighbor's data. This change makes the data easier to consume since VTK is widely used in the scientific community and tools to read and process these files are readily available (e.g.
