-------------------------------------------------------------------------- This foder contains a CAD file of trilobite 3-D model in STEP format (.stp) and two table contain datas of CFD simulations of queues of trilobites. -------------------------------------------------------------------------- S0 is the data of difference distances of trilobites following in queues, S1 is the data of a queue of 20 individuals. -------------------------------------------------------------------------- ************************* How to open the .stp file ************************* STP is a general format of a CAD 3-D model. You can use most of the CAD softwares to open and view it, such as freeCAD (https://www.freecadweb.org/) and OpenCascade (https://www.opencascade.com/) for free. Some commercial software also works such as Unigraphics NX (a CAD software of Siemens), Solid works, and Auto CAD. ************************* Thank you! *************************
