Folks,
I don't want to steal thunder from Dr. Tuković. But I want to report my implementation of Immersed Boundary Method (IBM) in OpenFOAM. Here is an example of flow over 3D sphere at Re=350. I also did 2D cylinder but the plot is not as exciting. The animation can be downloaded at my group's website. Enjoy! Last edited by liu; October 31, 2011 at 10:54. |

Hi Liu
Nice work Did you release your code? |

The code is not for prime time yet. Right now I only share it with my collaborators.
But eventually it will be out. So stay tuned.

Do you have any quantitative results yet?

Hi,
there will be a tutorial on Immersed Boundary Method by Dr. Tuković http://www.extend-project.de/OFWS/tr...thod-in-OF.pdf on the seventh OF workshop in Darmstadt. Does that mean that Immersed Boundary Method will be part of OpenFOAM-extend distribution? |

Sounds good and look forward to that.

The implementation of the immersed boundary method can be downloaded from the OpenFoam Workshop 7 material, uploaded by Holger Marschall.
Thank you Mr. Tukovic and Mr. Jasak for such a great contribution. Are there plans to add the functionality of using dynamic/moving objects? I've seen that in a presentation with a cylinder moving sinusoidally in vertical direction and two counter-rotating propeller. What changes must be done to the current implementation to achieve that? |

Hi everyone, I would be interested in the question I quoted as well. Does somebody have information about IBM in OF with moving geometries?? Any hints would be very appreciated =) |

Hello Foamers,
May i get your help? Indeed, I need to simulate 2-D oscillating cylinder with immersed boundary Mesh. Up to date, I have been able to write simple harmonic equation of motion in C++ (x''+w^2x=0). But the challenging task now is to map a 2-d cylinder within Open Foam that will be oscillating and again to mesh it is with IB not body fitted meshes. Can you help to know through which way, I will be able to make that solver? Regard! |

Can you help to know how i can find the force coefficient(drag coeff. and lift coeff.) in Immersed boundary tutorials in Foam-extend 4.0
How my controDict should be looking like? regard! |
