Some AMR calculations include a parameter that defines what region of a cell is covered, or filled, with valid data. The area of the cell where there is no data is indicative of a boundary in the simulation between two different fields. Specifically, the different fields are some variable that is being simulated, and another field that simply occupies space. Since these boundaries are not explicitly present in the AMR dataset, they must be extracted prior to visualization. Our work in AMR Embedded Boundary extraction and visualization spans a period of about 18 months with two sharp students from UC Davis. More information.
