The Rayleigh-Taylor instability benchmark

The Rayleigh-Taylor instability benchmark#

The shell script run_benchmark loops over viscosity values and wavelength values and for each combination generates an input file inputfile.prm based on the blank.prm file to which additional commands are added. The code is then run with inputfile.prm and the standard output is redirected in a temporary file ‘opla’ of no importance. Finally the viscosity and wavelength values are written to the ‘vy.dat’ file followed by the last line of the statistics. This file can later be processed with the ‘gnuplot_script’.

There is also the standalone input file rayleigh_taylor_instability.prm which runs only one of the cases (isoviscous and lambda=256km).
