Hi, do you know if is it possible to run an implicit LES in openfoam?
Dude, I love this. I tried just figuring this all out through trial-and-error, and everything always ended up looking like the monster from The Thing. I was starting to get a little frustrated until I found this video. Thank you so very much for this, very helpful.
A very good video, thank you for sharing.
Hi, thanks for the video, I am working on the staging problem in Ansys Fluent, also learned a lot from the overset mesh turtorials that you've made. Could you share this sumulation case with me? I would like to learn how to perform a dynamic moving mesh problem with overset mesh settings. Thanks a lot!
as soon as we have time we will prepare a video and share the case
fix your god damn cough jesus christ
You said @1:30 you will show us in a later video, how to setup this mesh. Did you already upload it ? Have you already uploaded a video showing how you created the mesh ? If not could you refer me some videos where I could learn this. Thank you in advance 😊
i think all videos are in the palylist. LEt me know, if you dont find we can prepare a short video.
For the advanced training of multiphase flow, do we have examples of lagrangian based cases?
You can find more training resources at this link: www.wolfdynamics.com/tutorials.html?id=118
Amazing openfoam training!
Excellent training videos! Just realised that these three cases are related to separated system. Is there any training tutorial for dispersed multiphase, in particular using Lagrangian method? That would be very helpful.
You can more training material at this link: www.wolfdynamics.com/tutorials.html?id=118
Hello, this kind of simulation is usually given the friction Reynolds number, I would like to ask, we know the friction Reynolds number, but do not know the Reynolds number, how to set the flow rate during the simulation?
Just a rule of the thumb. Roughly speaking Re = 20*Re_Tau up to a Re of 25000. After that you need to get some correlations or run precursor simulations.

Hi, do you have any documentation on the explanation of phi, phiv, and phid?
Well, probably is not the right answer, but you have the source code. phi* are the fluxes, depending of the formulation you are using different fluxes are used.
hi,sir ,Ihave a question that ***.vmx image can be used in wsl2 directly?
Yes, you just need to import it.
Please which software did you use for the mesh
ansys meshing
yes, that is correct
please edit out the coughing
Very useful video and tutorial files. Thanks!
Glad it was helpful!
Thank you very much for your generosity to share this on RUclips. @ 3:28 You showed that for LowRE simulation we need wall function for Omega. Would you please elaborate on that?
LowRE means no wall functions, that is, you are resolving the visocus sublayer. HighRE means you are using wall functions. The komega model is y+ insensitive.
after downloading it didnt show anything
Can you give more details?

Hi there! I have a foreground mesh (overset) generated from third party software, which has placed the overset patch at the end. So, simply copying the oversetPatch in the boundary file from the end and pasting it in the beginning wont work due to face number inconsistency. So, is there any way to solve this issue? (And my background mesh is generated using blockMesh and SHM, in which the oversetPatch is successfully placed in the beginning.)
Yes, that is covered in the videos. You need to use dummy patches. I dont recall the precise timestamp but we show two methods.
Same impression at first time, "why do I want to convert something to C in OpenFOAM?"

Check if you are loading the openmpi libraries. IT should work in serial and parallel out of the box.

I will say no, unless you use a program to resume donwloads
hey! is it okay to install stable diffusion and fooocus on the same system. I mean will it lead to any dependency collision? Tell me how are you running this both simultaneously? Did you installed both in different virtual environments...? in Please reply 🙏 please.........
yes, you can have both of them installed at the same time. Use both at the same time maybe is not a good idea unless you have got a lot memory
Hello! Can I ask you something? Where can I learn how to do like the video?
It is about dynamic meshing and overset meshes. Maybe one day I will prepare a proper video tutorial on this.
@@wolfdynamics5703 I'm really looking forward to this.
Amazing video! Do you have any courses or tutorials to do that?
It is about dynamic meshing and overset meshes. You can follow the overset videos on our site to get an idea how to set similar cases.
Is this same if the code used is in much older version like 7 or 8 of openfoam
There are a lot of differences. The case setup are completily different. Also, programming is different. Howevr, boundary conditions are very similar.
Thanks for this talk!
Extraordinary work for beginners! But is there any way to get the WSL distribution based on OpenSUSE 15.4 and come with OpenFOAM 9? It seems be replaced on website. Thanks a lot!
Can i use this tutorial with OpenFOAM 12?
Yes, you only need to update the scripts.
Thanks a lot. Really appreciate it.
Is it OK to use openfoam 10 for this training?
Yes, you only need to update the scripts.

Hi, with your configuration which is the maximum number of 3D elements you can run? I have an i7-1335U and I struggle to open something more than 14M, running is impossibile. It's possible to make these RANS simulations on intel i9? Thank you.
Well, depends of many factors. But if you are using a coupled solver, you will need a lot of memory. SEgregated solvers my rule is usually 1mill cells equal to 1GB RAM (roughtly speaking). In a notebook with 64 GB RAM I can run meshes of roughly speaking 50 mill cells.

how to create stl with multiple regions in cad modelling software
Not all CAD software support this. In onhsape I save the surface regions in different files. In some CAD tools you can save the geom in OBJ format and it will save the name of the patches, I think fusion3d and meshmixer support this feature.
@@wolfdynamics5703 for blockmesh greater the size of stl files that is my stl model is covered by mesh created by block mesh but only one region is changing while run snappyhexmesh (walls ) I have used different angles but same issue. Then I overlapped the surface of blockmesh and my stl file then it creates a same snappyhexmesh like stl files shape. I there any error in my doing can you explain please
Hi! Nice video! I have a simple question: looking at Omega and K values, I noticed that you used the wallfunctions at the wall. Since it is a wall resolved case, shouldn't we avoid that?
The KOmega turbulence model is y+ insensitive. The wall function will take care of the treatment
@@wolfdynamics5703 so they basically will ignore the wall treatment if y+ < 5 ?
@@antoine1407 it is better to say, it will automatically use the right treatment according to the y+ value
8:05 i think in the code expression the last expression will be fvm::laplacian(nu, fvm::div(T)) according to the expression, i am always accepting to be corrected if i am wrong
doesn't it have staggered grids for solving, because of collocated grid it can cause checkerboard problem
Yes, it is a collocated solver.

Hi there! I'm just starting out with OpenFOAM, and don't have prior experience with 9/10. Is there any plan for a roadmap which combines your currently available resources, aimed at new learners?
well, my advice is to stay with OF11 and don't look at previous version. They are very different and it will confuse you.
@@wolfdynamics5703 i'd like to do that- that said, I'm having difficulty finding tutorials to take me through introductory cases, the way your series on OpenFOAM 9 and 10 does.
