README - guide to data deposit files for article 'Keels of boxfish strongly improve stabilization against roll' Folder legend: 'STL input files': carapace surface mesh files used as input in the models. 'Force Roll Fluent CAS & DAT': ANSYS Fluent 19.1 CAS (model configuration file) and associated DAT (fluid flow data file) for roll simulations at 40 time steps (at 0.004 s per time step; flow time 0.16 s; velocity 6.4 rad/s). 'Fluent output Roll moments.zip': ASCII files (.out) with columns (1) time and (2) hydrodynamic moment about the roll axis through the centre of volume of the carapace for all forced roll simulations described in the article. 'Steady flow Drag Yaw Pitch: ANSYS Workbench 19.1 files and linked data folder (_files) containing all steady flow simulation data described in the article. Data folders need to be unzipped to be opened. File name legend: 'KEELS' or 'REDUCED KEELS': the input surface mesh model has reduced (flattened) keels relative to the orignal scan. Full species names: Acanthostracion guineensis; Lactophrys triqueter; Lactoria cornuta; Ostracion cubicus, Rhynchostracion rhinorhynchus. acc40 = simulation at constant 40 rad/s^2 rotational acceleration pitch20= model at 20 degrees pitch angle of attack yaw20= model at 20 degrees yaw angle of attack zero_degrees= model at 0 degrees angle of attack
