Dataset for "A steeply-inclined trajectory for the Chicxulub impact"
<p>Data files for 5 timesteps from each simulation. File name convention is A<angle>_v<velocity>_t<time>.npz where time is in seconds (or the string "final").</p> <p>Each file contains several cell-based fields (pressure, temperature, specific internal energy, density), tracer fields (peak tracer pressure, x,y,z locations) and grid information (nodal and cell-centred coordinates). For an example of how to access all that information, see the "Timestep" class at the top of the "plot_frame.py" python script.</p> <p>Python script "plot_frame.py" will create a figure similar to the panels in Figures 2 and 3 in the paper. Use the flags -a, -V and -t to set the desired impact angle, impact velocity and time.</p> <p>iSALE3D input files for the 8 simulations can be found in inputfiles.tgz</p> <p>Postprocessing python scripts can be found in postprocessing.tgz</p>
