Adaptive Mesh Refinement (AMR) | OpenFOAM

In this tutorial, we will see how to implement adaptive mesh refinement feature in OpenFOAM. Using air bubble rising in a water column case, which is a Volume of Fluid (VoF) method based multiphase problem.

please make video of nucleate boiling and generation of bubbles by VOF and interfoam. Thanks

Thank you, we really appreciate your effort, My question is
Can I use AMR for my 2D water entry problem by using overInterDyMFoam solver.
I mean when you work with overset mesh, maybe it will be difficult to use AMR.

[easyhack]

you are wonderful. you are no longer active on youtube as we miss your presence because your teaching style is very easy and understandable. so please come back to youtube and be active. Thanks

Congratulations!
Maybe you could try a 4th option: the 25600 mesh with AMR. However, AMR of just 1 extra level, done only every 2 to 4 time-steps and setting the refinement for a larger region around the interface. That might be a good performance-efficiency compromise.

When you give the results of three calculations, in the case of AMR, there is a problem of describing the vortex behind the bubble. In the first and second cases it is. I understand this is the choice of the adaptation parameter?

Thanks for the explanation. I have done the same to check drop falling. I have downloaded your file and pated in the control directory to run the simulation. But mesh did not refine. I am using OpenFoam10. Let me know if you have any suggestions. Thanks.

In this case of blockmeshdict file you used the vof case blockmeshdict file or different one because in previous problem (vof) ncells is 24000 and in this video the ncells is 3200 .
i tried thid simulation with your previous case (vof) blockmeshdict file and it is taking too much time. please guide me on this

I am using this tutorial to simulate a shock wave impact on a water droplet, I made all steps you said but when I run my solver "compressibleInterFoam" it doesn't seem to work, do you know any possible reason?

[amirhosseinparvin]

Thank you. I want to know is it possible to do mesh refinements for two phases interfaces for multiphase calculation? like alpha.water and alpha.sed?

[fundamentalsofmechanicalen]

Have you any idea about? How can plot Skin Friction Coefficient Vs Reynold number graph with the help of gnuplot

[trongnguyenduy]

is it possible to run AMR technique in parallel mode? I have tried but the simulation crashed.

[fundamentalsofmechanicalen]

Please provided post processing result of any case and how to plot different graph with the help of gnuplot

[trongnguyenduy]

why is simulation with AMR techniques is much longer than the third one during its cell number seem much lower (3200 cells compared with 25600 cells)?

[NeelarunMukherjee]

Hey can you please make a video where I can use a steady solver to perform the AMR. Apparently, interFoam is a AMR modified solver inbuilt in OF.
