Dear Professor Hjasak
My name is Javier Basurco I am doing my PhD in Mechanical Engineering in Rio de Janeiro. I am working with modeling of slug flow of air - water two - phase flow. I am using Fluent to simulate this pattern. When I know the OpenFOAM I stay very intersted in about the software. In the first moment I am compare my solution from fluent to OpenFOAM with VOF method my next step is implement a level set method to compared which method reconstructed better the interface.
I woul like to advice in this way, I really appreciated your advice to programming. Thanks for the pacience Respectfully Javier Basurco Quote:

May I ask for the paper as well?

Hi Gonzalo,
You can get the paper from the Open Source CFD 2007 conference proceedings here. Are you working/planning to work with level set? I am tying to develop some bubble model with it ... but is work in progress :) ... |
Actually not yet, just gathering info :)

paper
Hi...
I am using level set method to study the interface behavior in two phas flows (surface aeration). I came across the link to below paper by Bitan Shu. Would it be possible to refer to this paper ? Implementation of level set method based on OpenFOAM for Capturing the free interface in incompressible fluid flows my email address is akforu2000@yahoo.co.in |

Thanks Gijs,
I checked the link. However could not download it due to some internet problems. Can you send the soft copy. My email address is akforu2000@yahoo.co.in Thanks Ajit |

Thanks Gijsbert.
Received both the article and ppt. Thanks Ajit |
level set with VOF MODEL fluent
Am currently working with the motion of a single bubble in a flowing fluid. I didnt understand what you said in youre comment about re-initialization and running the solver seperately for the second one. I am relatively new in fluent and am having trouble how to couple the level set function with VOF model. Can you take some time out and provide me with a step by step process (or a tutorial ) on how to do that ? Will be grateful.My email address is ishancd@yahoo.com

ishan,
this is OpenFOAM not Fluent. But for coupling level-set and vof read the articles of sussman, and the ones which reference him! Theres a lot out there. Best Kathrin |
Hallo Matthias,
did you find out what BC's need to be set? If so could you give me a hint? Friederike |
Inplementation of Level Set
Hello,
I am very new in OpenFoam and I am working in the implementation of Level Set in interFoam solver. I created the fields necessaries for the method; however, I don't understand how I can initialize the level set function. Can help me? I am reading Implementation of the Level Set Method into OpenFOAM for captiring the Free Interface in Incompressible Fluid Flows by Bitan Shu. Thank you |
Hey Marco,
initializing the level-set-function can be done by using the application funkySetFields which is part of swak4foam. https://openfoamwiki.net/index.php/Contrib/swak4Foam Best regards Friederike |
Could anyone in this thread send Bitan's paper to me? Thank you in advance!

Hi, Gijsbert.
Could you send the paper to me? Thank you very much!!! Best regards, Wen |
Hi Wen,
Sorry, can't find the article. I guess the best would be to ask Bitan Shu personally: http://www.tecies.de |
Thank you for the link!

field intialization for level set
Hello,
Is there anybody who have successfully implemented Level Set in OpenFoam? I have some questions about the implementation. How Should I initialize the field? I have read that I can do this with funkySetFields but I couldn't figure out how to initialize the field as a signed distance function from the interface. I also have some questions about the flux calculations. Thanks for your reply in advance |
Could you tell me how you reinitialize the level set field?
regards, Wen |
