![]() I have used the heapsort algorithm in a hierarchical agglomeration schemeĭeveloped and implemented in NASA's FUN3D code. Example cases are included: MMS test, cube, hemisphere cylinder, and ONERA M6 wing. Read the source code and learn how a node-centered edge-based unstructured-grid solver is written. This is an implicit unstructured-grid Euler solver (f90, serial, tetra only), written for an educational purpose. Grab this code, and learn how it can be implemented. MMS has been widely used for verifying the order of accuracy of a CFD code. That is,Īny function v(x,y,z) is an exact solution to the following equation: Any function can be madeĪn exact solution to the 3D Euler equations with suitable source terms. Manufactured solutions (MMS) for the 3D Euler equations. This code shows how to compute the source terms in the method of su2 file for SU2, and tecplot and vtk files for viewing the grid.Įducationally-Designed Unstructured 3D (EDU3D) ugrtid file (for a solver such as FUN3D). ![]() Below, a flat-plate grid is used as an example. ![]() Generated for a pure triangular grid as below. Will be generated for a pure quadrilateral grid, and a prismatic or tetrahedral grid will be This program reads a 2D tria/quqad/mixed grid, and generatesĪ 3D grid by extending/rotating the 2D grid to the third dimension. "I do like CFD, VOL.1, Second Edition" is now available in both printed and PDF versions.ĬFD seminar at National Institute of Aerospace is now broadcast online!Ĭheck out the website for seminar videos and files -Įducationally-Designed Unstructured 2D (EDU2D)ĭownload all files: edu2d_twod2threed.zip [Note: As the name, Katate Masatsuka, implies, More sample programs are coming up: Delaunay triangulation code,Ī panel code for an airfoil, 2D unstructured Navier-Stokes code, etc. ![]()
