Hi Foamers,
I am quite new to CFD, especially with OpenFoam. My case is 2D and using the buoyantPimpleFoam solver and I would like to know if I should mesh my geometry rather with triangle or quadrangle? Is there any rule about how to decide which one I should use? Also, on my physic system, I have sharp angles but I know I should put fillets instead. What is the minimum radius to be used? (currently using 0.1 but I choosed a random value...) Thanks for helping! Last edited by NoradFirst2; June 9, 2015 at 03:53. Reason: Precision |

Hi,
blockmesh creates "hexahedra" mesh -> good mesh for CFD there is a tool called polyDualMesh: It is used to generate a “honeycomb” polyhedral mesh from a tetrahedral mesh. “honeycomb” polyhedral mesh -> good mesh for CFD What tool do you want to use for your meshing? read http://openfoamwiki.net/index.php/Sn...als_and_Guides http://upcommons.upc.edu/pfc/bitstre...9/1/memory.pdf STUDY OF MESH DEFORMATION FEATURES OF AN OPEN SOURCE CFD PACKAGE AND APPLICATION TO A GEAR PUMP SIMULATION ->2D mesh with snappyhexmesh http://www.cfd-online.com/Forums/ope...s-meshers.html |

Thanks for answering, I am using SALOME to mesh.
