Hi Abe,

Thanks for reminding me to make the geometry files available. I’ve added a link to the geometry files in the particular tutorials. I hope, this helps.

Jens:

I’m trying to follow the tutorials you posted, however, I couldn’t find any link where I can download hull.stl or kcs.stl files. Could you let me know where I can get those files so that I can go through your tutorials?

And what are you trying to simulate? Is it just ship resistance, or do you wish to account for the ship motion as well?

Hi Jan, Just in case you haven't found out yet: Just try the OpenFOAM forum and the SIG Ship Hydrodynamics. What are you planning to do? Jens

Awesome site, great info. Where can I get more info on what you do with OpenFOAM and ship hydrodynamics?

Hi Felipe,

First an advice on the usage of snappyHexMesh: In principle you cannot use it to generate a 2D mesh, if you apply any refinement. This is due to the fact that snappyHexMesh refines cells by splitting them in all directions. As a matter of fact, you will obtain more than one cell in your desired empty direction. A workaround could be, not to use the refinements and create a sufficiently fine background mesh.

I am not a Rhino expert and cannot give you any advice on how to simplify the geometry generation in Rhino. There should be something like a scripting console? But if the cross-section of the airfoils can be described mathematically, you can try to create the airfoil e.g. in python and use VTK to generate an STL from that.

Hey Jens I have a question concerning the stl file
generation. I want to simulate the flow around an airfoil in 2D
with OpenFOAM. Therefore I want to use snappyHexMesh, but I need
the stl file of the airfoil. Do you have any suggestion about how
could I do in a way that can be simply (I will simulate a family of
airfoils). Thanks in advance Felipe

The refinementLevel describes how many times each edge of a cell is sliced into two parts. For a hexahedral cell, a refinementLevel of 1 gives 8 cells (2 times 2 times 2) and so on.
