[@Tommybotham]

This is not a complete tutorial... You have edited some of the files in system and you have not shown what you have done. blockMeshDict for example has "upperWall", "lowerWall" and "frontAndBack", whereas our geometry has just wall. I have no idea what values to put in the matrices for wall. Running this setup throws errors. So this is another frustrating, incomplete OpenFOAM tutorial.... I get this error: "--> FOAM Warning : From void Foam::polyBoundaryMesh::calcGroupIDs() const in file meshes/polyMesh/polyBoundaryMesh/polyBoundaryMesh.C at line 100 Removed group 'wall' which clashes with patch 2 of the same name. --> FOAM Warning : From Foam::labelHashSet Foam::polyBoundaryMesh::patchSet(const Foam::UList&, bool, bool) const in file meshes/polyMesh/polyBoundaryMesh/polyBoundaryMesh.C at line 915 Cannot find any patch or group names matching lowerWall --> FOAM Warning : From Foam::labelHashSet Foam::polyBoundaryMesh::patchSet(const Foam::UList&, bool, bool) const in file meshes/polyMesh/polyBoundaryMesh/polyBoundaryMesh.C at line 921 Cannot find any patch names matching lowerWall Sampled surface: nearWall -> vtk sampledPatchInternalField: nearWall : patches:1(lowerWall)" EDIT: seems to run now. The only change I made was making sure that deltaT = 0.0001. However, my point stands with the blockMeshDict file. Why does it still run even though upper/lower/front and back are mentioned there? And if I want to only mention "wall", how do I find the values to put in the matrix?

[@vaibhavvb9898]

I know this is a bit late and you probably would have figured it out already. But for those who are curious about it, Openfoam just searches for the boundary condition for the patches in constant/polymesh/boundary and it does not matter if there are boundary conditions for non existent patches in your files.

[@onurerdincler3107]

This got me excited about going back to openfoam again and experiment after hopelessly struggling with that 90 degree elbow flow tutorial during my uni years

[@interfluo6420]

I had a similar experience but I wasn't even able to install it. I definitely recommend trying it out again, once you work out a few simulations the software becomes fairly intuitive, Good luck!

[@miiortbiiort4610]

Oh wow! I just started learning OpenFOAM two weeks ago and I'm in the exact position you described. Its really difficult to find actually helpful (beginner focussed) content out there :(. Thanks for making this! :) I did have a question if you have the time. I'm trying to simulate airflow around an air rifle pellet (basically a bullet) as if in a wind tunnel. How do I best go about setting up the original case folder? I could indeed just copy a folder like the motorBike tutorial, but every file there already seems customized to fit the motorbike.obj model. Is there a more basic way to create a case folder that works for general models or does that require extensive knowledge beyond a beginners capacity?

[@interfluo6420]

Hey, thanks for the comment! The general procedure I follow is first defining the flow type and solver I am looking to use. In the case of an air rifle pellet I would think that you most likely want to use a solver for a compressible flow. I would then find the example with the most similar boundary conditions to the ones I am trying to simulate. In the case you explained I would likely use: tutorials/compressible/sonicFoam/RAS/nacaAirfoil directory. Hope this helps

[@designsandsimulations887]

is it possible to create geometry on OpenFOAM without using ANSYS software?

[@Tommybotham]

@@interfluo6420 Yeah but, don't boundary conditions reflect the geometry of the mesh you're using? A bullet has a different shape to an airfoil, how do you set boundary conditions on the exact geometry of the bullet?

[@quanboli-yr1hv]

You need to change the definition of the boundaries for each parameter file in the 0 folder, when anasy divides the mesh you need to remember your naming and define the different boundaries according to the naming

[@Rubafix989]

Thanks a lot. I was at a loss when simscale severely limited the community offer to only 10 simulations. OpenFOAM is not as intuitive but seems quite powerful.

[@yatbuunchoi]

Good Tutorial. A few comments. You missed where to set the model in the constant folder. I know it's LES, but say someone wants to go with a RAS KOmegaSST model instead. Maybe it's out of the scope of the tutorial. Also, it would be helpful to go over the boundary conditions. For instance, why is there an inletOutlet condition on the outlet of U and what is a turbulent inlet condition. A lot of tutorials miss explaining what boundary conditions are and OpenFOAM is very sensitive to them. The angle you're taking in your tutorials is great and needed, thank you and keep it up.

[@interfluo6420]

Thank you for the comment, I will definitely take it into consideration for future videos

Thank you a lot! I am learning to apply LES in building ventilation simulation in bluecfd and I find this video very helpful and straightforward! I have a very simple question: why do we use OpenFoam to do simulation if we have Ansys Fluent? What's the advantage of OpenFoam compared to Ansys Fluent?

[@interfluo6420]

Several reason, the main one when I first started was that I only had access to an academic license (limiting me to 500,000 cells). Since then I have really come to like openfoam, having direct access to the code opens up a lot of possibilities and I honestly also like the workflow and file system used for openfoam.

Hi. Thank you for your tutorial. Unfortunately m, I was disappointedat. I mean the content of the video and its description are not identical: No focus on how to setup the case, no focus on the turbulence model, why to choose that model, how to set its coefficients, how to set the boundary/initial conditions in 0 folder. The main focus was only on mesh generation which is relatively easy compared to case preparation and proper setup itself.

[@interfluo6420]

I have some more in depth videos coming up, this one was really geared towards beginners. You are correct, I assumed people would be able to find a close enough example in the tutorial folder that they wouldn't have to worry too much about the actual case set-up, that is why I went over that part pretty fast.

So I know that EOF errors occur when the program unexpectedly encounters the end of the file. This is likely cause by a missing parenthesis or semi colon somewhere in that dictionary. Unfortunately I don't know of any easy way of doing this besides checking all of the files manually, the problem shouldn't be in the files I uploaded unless their was an error when you downloaded them, it appear to be in your db/dictionary/entry/entryIO.C at line 165.

Any help would be really appreciated, thank you. Also, besides this error, how should we setup the 0, system and constant folders' files ?

[@interfluo6420]

The only two thing I can think of is to make sure your mesh file is in the correct location (you should have your folder containing 0, system, constants, and .msh file); the other thing is to make sure that you export the mesh in the correct format (I show how in the video). If you watch some of my newer videos I go a bit more into depth on how to set up the 0 folder, but I honestly haven't done a full length tutorial yet because it changes a lot depending on solver and turbulence model used.
