In the case of blunt bodies such as buildings, unlike airfoils, the drag is dominated by the pressure forces and is less sensitive to viscous drag effects.

Luckily FreeCAD allow us to do both, the beauty of open I, unfortunately, struggled to follow the videos, but in principle the inviscid analysis should be able to provide you with a reasonable first-order estimate of the flow. Qingfeng are, however, are interested in FSI and has said that he would like to see an integrated capability. We love GMSH, but we often need to generate large meshes (> 1 M cells) for flow analysis and we think it would make sense to move to cut-cell Cartesian meshes (snappyHexMesh and/or cfMesh). For example, for practical CFD work we need to look at some other meshing strategies. We do foresee some differences between the two in the future that might make sense to have to seperate capabilties.

From our perspective, we want to keep the link as close as possible and ensure there are not duplicating code, but seeing that we aim this fork at the beginner we want to keep it clean and simple. We really hope the community would find this The CFD WB makes heavily use of the FEM functionality, but Bernd suggested a while back to Qingfeng that it might make sense to start a new WB. We have created step-by-step training material for the workbench at Īny comments and feedback will be appreciated. * Extension to turbulent using RANS (k-w SST). * Cut-cell Cartesian meshing with boundary layers. * Tetrahedral meshing using GMSH including multiregion meshing (using FEM workbench functionality). * Flow initialisation with a potential solver.

* Incompressible, laminar flow (simpleFoam). Our version with installation instructions can be obtained from ( Edited: The name has been changed from Cfd to CfdOF to allow the fork to coexist with the original). After discussion of the different philosophies we felt that a fork was maybe warranted. The aim of this wokbench is to assist OpenFOAM beginners to get up and running rather than to provide advanced functionality (such as fluid-structure interaction). We have created a fork of the CFD workbench of Qingfeng Xia ( ).
