The data consists of seven HIGRAD/FIRETEC simulations, each with multiple time series (each 70 to 100 times steps) of 3D scalar fields on a curvilinear grid from coupled Higrad/Firetec simulations. These .vts (VTK structured grid data format, can be opened using Paraview) files were generated to study a phenomena known as vorticity-driven lateral spread in mountain and canyon topographies. There are six mountain and one canyon scenario. Simulations names are first tagged with the topographical structure - either mountain or valley. Mountain simulations are then tagged with either head curve or back curve to indicate whether the fire starts as a headfire or a backing fire and that the simulation is a part of a suite of simulations exploring the influence of the radius of curvature along the ridgeline. Finally, a numerical value is associated with each simulation - 40, 80 or 320. This value determines the radius of curvature or roundness of the peak of the mountain. A higher value indicates a more rounded ridgeline, resulting in a gentle hill top as opposed to a sharp pointy ridge. For questions, please contact Divya Banesh, dbanesh@lanl.gov.
