What does the following bullet in the foam-3.0 release statement mean?
** Library-level support for Immersed Boundary Method and Overset Mesh I searched through the src tree for these items, but could not locate them. Thanks! Kevin |

Greetings Kevin,
I suspect that "Library-level support" means that it's plug-n-play ready for connecting with the paid features for IBM and foamedOver... (note: I'm assuming they're paid, because I haven't found any public repository for them yet) You might want to ask about this directly in the announcement page: http://www.cfd-online.com/Forums/ope...end-3-0-a.html Best regards, Bruno Last edited by wyldckat; January 10, 2014 at 20:56.

Hi,
I guess that "Immersed Boundary Method" should be integrated completely into new release: "foam-extend-3.0", as the first publication of Immersed Boundary Method material was at http://openfoam-extend.sourceforge.n...7_Program.html The Dynamic Overset Grid implementation comes from http://celeritassimtech.com/ read more from their website. It is a commercial product, so I guess foam-extend-3.0 is prepared to make use of Overset, but you have to buy it (If you are qualified to buy it anyway there are some restrictions because military money made this technology) |

Thanks for the information! I searched around for the class types mentioned in that paper "immersedBoundary*" and did not find anything in the current foam-3.0 code. I don't think it has been integrated at all actually. I suspect "library support" means you can plug something into foam-3.0 and it can do IBM and overset.

As far as I understand the suggar++ library isn't ITAR controlled, the integration of this library with OpenFOAM (foamedOver) however is. As long as you are from a country that can acquire US weapons you should be able to license suggar++. foamedOver is property of the US Navy.

I was trying to port the implementation of IBM method done in 1.6-ext to extend-project-3.1. I am particularly interested in simpleIbFoam. I compiled everything else I believe but the simpleIbFoam source code was not compiled. I came to the conclusion that "Library-level support for Immersed Boundary Method and Overset Mesh " means that the libraries that were used in the previous version, meaning
surfaceNormal surfaceInvertNormal immersedBoundary immersedBoundaryForce makeTriSurfaceMesh refineImmersedBoundaryMesh could be compiled in the new version. However, I found that those solvers are not compiled. I would appreciate any comments |

Is there anything new regarding the availability of overset library in foam-extend?
I've been loooking for it in the sources but I dont't find anything. Will it be released in a future foam-extend version? |

Hi Vincent,
my guess is that overset grid (implemented by wikki) will not be published. But if you compare how long Immersed Boundary Method (IBM) was in wikki´s software repo and when it was released to public it gives a good comparison when they might publish overset grid in extend. Another question what meshing software could you use if overset would be published in extend. Pointwise supports PEGASUS 5 software from NASA Ames Research Center and the Suggar++ software from Celeritas Simulation Technologies. If wikki did not use Pegasus (and that has licensed as well to mesh in pointwise) what could be used to work with overset grid |
