It would be really great if you all can send me this "Implementation of level set method based on OpenFOAM for Capturing the free interface in incompressible fluid flows" Bitan Shu, Frank Dammel, Peter Stephan - Technische Universität Darmstadt, Germany which was presented recently at the OpenFOAM International Conference. |

I am glad to see that you are also interested in the LSM. If anyone wants the paper, please drop me an e-mail. Regards, Bitan Shu |
I currently try to implement a
I currently try to implement a level-set equation into OpenFOAM for a simulation of flame propagation.
As I see Bitan probably used a structured grid for the gradient calculation within the reinitialization of the distance function and implemented an own discretization scheme for the gradients (WENO). Can anybody give me a hint how I could deal with the reinitialization of the distance function on an arbitrary unstructured mesh? My Problem is as follows: During the transport equation step I actually solve as first test the simple equation fvm::div(phi,gmean) == 0 In a second reinitialization step I have to solve the equation mag(grad(gmean)) == 1 for all regions where gmean!=0 to reinitialize the distance function. My problems is now that I use zeroGradient for the boundary conditions of gmean during the transport equation step which is not valid for the reinitialization. How can I deal with the patch gradients in that case? Has anybody done anything similar? regards, Matthias |
Yes, I have done level set. M
Yes, I have done level set. Make two fields, with different boundary conditions. Run the normal solver on the first, reinitialisation on the second and copy the result.
Enjoy, Hrv |
Hrv, thanks a lot for your qui
Hrv, thanks a lot for your quick reply.
Yes your idea is straight forward. Can you give me a last hint? Is there a boundary condition already implemented which will fit for the reinitialisation? Cause I need neither fixedGradient nor zeroGradient, it would be a kind of fixedMagGrad, wouldn't it. greetings, Matthias |
Has anybody a hint for me, how
Has anybody a hint for me, how to deal with the boundary condition during the reinitialization of the level-set function?
I would be very grateful, Matthias |

Hi,
I am wondering if anyone here has successfully implemented Level Set into OpenFOAM and is willing to share the code? Pei |
Look for Shu, Stephan papers. They implemented the code in OpenFOAM
Dhir too, but not in OpenFOAM. |
Hello,
has anyone managed to implement the level set formulation as proposed in the paper by shu? 1)In particular, have you managed to implement the the gradient term (eq (11-12)) for the reinitialization procedures? 2)and also, I have some strange velocity pressure peaks at the interface whenevr the interface change cell, has anyone had the same issue?any solution? The error come sprobably to some non smoothnes of the rhoPhi term, or nu but I can't solve it..(yes, i applied smoothing as suggested..) Thanks, Matteo |
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:

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 ?

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 |
