Hey Bruno,

Thanks for the help. I was able to get it going. I was wondering if you could please inform me if it is possible to import a file already meshed in Rhino into OpenFOAM and still be able to distinguish boundaries?

I received some STL files but they are in binary mode and I cannot open them in OpenFOAM. I was hoping if it is possible to somehow define the surfaces in Rhino, mesh the structure, import to OpenFOAM and still be capable of defining boundary conditions to each desired surface instead of the structure of a whole.

Cheers

Lucas

Hi Lucas,

I've moved your post from the other thread: http://www.cfd-online.com/Forums/ope...ionfoam-3.html - since this question is completely off-topic of the other thread.

I'm not familiar with Rhino, but in order to preserve surface names from STL to OpenFOAM's patches, you'll have to rely on using ASCII STL files and to use the same structure used by snappyHexMesh.

The easiest for understanding this is to do the opposite, namely to convert patches in OpenFOAM to STL. For example, if you go into an existing case for which you already have an OpenFOAM mesh, then run:

foamToSurface test.stl

you'll get a file "test.stl" in ASCII, where each "solid" block of code is respective to a patch.

Give SwiftSnap a try, since it relies on Blender for handling the geometries and helps set-up the "snappyHexMeshDict" file: http://openfoamwiki.net/index.php/Contrib/SwiftSnap

Best regards,
Bruno

Bruno,

Thanks for the response! I will check on that!
Obrigado!

In rhino you can first make a simple mesh of your geometry. Use setobjectname to name your boundaries. export the mesh to an obj file (object names will not be maintained in stl files from rhino). The patches shall now be identifiable when you proceed with sHm.
