CFD simulation of the wind over a terrain
Dear all,
I have to perform the simulation of the wind over the terrain of a certain area. I start from a DTED map. I would like to know which are the steps I have to do in order to get some good results. Also, the software I wish to use is OpenFOAM. Thanks a lot, Samuele |
Do a google search for "bolund experiment" you might get some useful links and hints.

Never hared about it.
Let's try. Thanks a lot. Samuele |
Hi,
have a look at http://www.cfd-online.com/Forums/ope...-openfoam.html http://www.cfd-online.com/Forums/ope...tml#post260727 there was also s.th at http://openfoamwiki.net but I do not have the link the post http://www.cfd-online.com/Forums/ope...tml#post256941 is very useful Terrain digital elevation maps (DEMs) => .Obj => STL from STL together with a suiting Blockmesh you can snappyhexmesh you terrain |
Hi Elvis,
thanks a lot. I will study the links you sent, tonight. Then I'll let you know. Keep in touch, Samuele. |
Hey Elvis,
one more question: could you explain how I can pass from the Terrain digital elevation maps (DEMs) to .Obj and then to STL? I am working hard on the "turbineSitting" tutorial.. And I hope to cope with it as soon as possible! Samuele |
Hi Samuele,
I do not know how Terrain digital elevation maps (DEMs) are converted to .Obj-files! But .Obj ->.STL can be converted via any VTK-based Software (for example paraview http://paraview.org or Mayavi (1 or 2) http://www.vtk.org/doc/release/5.8/html/a01304.html =>vtkOBJReader http://www.vtk.org/doc/release/5.8/html/a01973.html =>vtkSTLWriter http://www.vtk.org/doc/release/5.8/html/a00523.html => vtkDEMReader well it looks like that you can read DEMso you also can write via vtkSTLWriter all within VTK or MeshLab http://meshlab.sourceforge.net/ The Bolund experiment => http://web.student.chalmers.se/group...SlidesOFW5.pdf |
