Abstract:

Results files from computer simulations of fluid flow for 3D models of Ediacaran organisms and communities, generated using computational fluid dynamics. Simulations performed using the simulation software package COMSOL Multiphysics. Root folder names refer to initial trials ‘Cylinder Tests’), modern organisms (‘Chondrocladia lyra’), Ediacaran organisms (‘Pectinifrons’ and ‘Pterdinium’), and Ediacaran surfaces (‘Avalon’ and ‘White Sea’ surfaces). Sub-folder and file names refer to simulations performed with different models (e.g., ‘Base’, ‘Filled’ and ‘Flush’ Petridinium models), model orientations (e.g., 0°, 90°, and 180° to the inlet), current velocities (e.g., 0.15, 0.5 and 0.85 m/s), and turbulence models (e.g., Spalart Allmaras, shear stress transport, and large eddy simulation). Further details for Pectinifrons and Pteridinium available in Darroch et al. 2022 (https://doi.org/10.1017/pab.2022.2) and Darroch et al. 2023 (https://doi.org/10.1016/j.isci.2023.105989), respectively. Files can be opened with COMSOL Multiphysics (www.comsol.com) versions 5.6 or 6.0 and above.

statement:

In each simulation, the relevant 3D model was first imported into COMSOL. A computational domain consisting of a hexahedron was then created, with the material properties of water assigned to the space surrounding the model. An inlet with a fully developed flow was specified at one end of the domain, with a zero-pressure outlet at the opposing end. No-slip boundaries were assigned to the model and the bottom of the domain, with a slip boundary used for the top of the domain. The domain was meshed using prismatic elements along no-slip boundaries, with tetrahedral elements used in the rest of the domain. Inlet velocities were simulated to reflect the typical range of current speeds recorded from analogous modern environments. The Reynolds-averaged Navier–Stokes equations were solved using the Spalart-Allmaras model, the shear-stress transport model, or an alternative turbulence model.
