Three-dimensional DNS data and associated movies (gifs) for the five main cases B2, B5, B6, B8 and B10 in the paper "Stratified inclined duct: direct numerical simulations". The reservoirs have been cropped out so that only the duct domain is kept, i.e. (x,y,z) \in [-30,30]x[-1,1]x[-1,1]. Each dataset B2, B5, B6, B8, B10 consists of 46 snapshots starting at t=80 (after any initial transients) and until 260, spaced by 4 (nondimensional advective time units). B2-B8 are provided at the resolution 92565121 (as in Table 1 of the paper, noting only the duct is kept, without reservoirs). B10 is provided at 128565145 (given the higher Re=1000). Additionally we provide the high-resolution version of B10 at 2571121121 (as in Table 1), but at a reduced temporal resolution (16 snapshots from t=80 to 260 spaced by 12). Please contact the authors directly if you wish to obtain data at a higher temporal resolution or other data discussed in the paper.
