Title 3-D model of Parvancorina minchami from South Australia in STL format
Downloaded 11 times
Description A freely-available reconstruction of Parvancorina minchami from South Australia in dorsal view (https://en.wikipedia.org/wiki/Parvancorina#/media/File:Parvancorina_species.png) was imported into the open-source 3-D creation program Blender (http://www.blender.org) and used as a reference to guide box modelling of the shield-shaped base. The file was exported from Blender in STL format and converted into a non-uniform rational basis spline (NURBS) surface (IGES format) in Geomagic Studio 2012 (http://www.geomagic.com). This IGES format file was then imported into the commercial simulation software COMSOL Multiphysics (https://uk.comsol.com/), where the raised T-shaped ridge was digitally modelled with a half torus, a cylinder, and three spheres. The final model was exported from COMSOL in STL format.

Title CFD simulation file for Parvancorina minchami from South Australia, original relief, oriented at 0° to the current, MPH format
Downloaded 6 times
Description Computational fluid dynamics (CFD) simulations of water flow were performed in COMSOL. A model of Parvancorina minchami from South Australia with original relief was oriented at 0° to the current and was fixed to the lower surface of a half-cylinder. Three-dimensional, incompressible flow of water was simulated with a normal inflow velocity inlet at the upstream end of the half-cylinder and a zero-pressure outlet at the downstream end. Slip boundary conditions were assigned to the top and sides of the half-cylinder, and no-slip boundary conditions were assigned to the Parvancorina model and the lower surface of the half-cylinder. The domain was meshed using free tetrahedral elements and the shear stress transport turbulence model was used to solve the Reynolds-averaged Navier–Stokes equations. A stationary solver was used to compute the steady-state flow patterns. Simulations were performed with an inlet velocity of 0.1, 0.2, and 0.5 m/s.

A model of Parvancorina sagitta from Russia with relief increased by 15% was oriented at 90° to the current and was fixed to the lower surface of a half-cylinder. Three-dimensional, incompressible flow of water was simulated with a normal inflow velocity inlet at the upstream end of the half-cylinder and a zero-pressure outlet at the downstream end. Slip boundary conditions were assigned to the top and sides of the half-cylinder, and no-slip boundary conditions were assigned to the Parvancorina model and the lower surface of the half-cylinder. The domain was meshed using free tetrahedral elements and the shear stress transport turbulence model was used to solve the Reynolds-averaged Navier–Stokes equations. A stationary solver was used to compute the steady-state flow patterns. Simulations were performed with an inlet velocity of 0.1, 0.2, and 0.5 m/s.
