It's no openFoam tutorial if i need ansys for the mesh...

One the Best tutorial among all the videos on openfoam , appreciated the work!

The solution is to use Solidworks and Solidworks Visualize. Anything else in the polygon world is a waste of time.

New subscriber here. Can we discuss a new test of the valve in open foam but with the valve installed in the pulse detonation chamber it was designed for that has a pulsed pressure higher that atmospheric? I’ve never seen the simulation being ran in the proper format for use of the invention. It will yield very different results!

Does the use of designmodeler add anything or is it just geometry creation. Us non commercial users are stuck with open source software

So...tetrahedral mesh had 2.36x as many cells, 0.99x as many nodes, and 1.62x as many edges...as mixed mesh. That's a big deal if run duration was only 0.73x! Why isn't this common knowledge already? Good work! Did you run exactly 10,000 iterations for each case? It appears so from the charts, but it's hard to tell with a logarithmic domain and holes in the data. 2:11 On the right-hand chart, what the hell's going on with the y-axis? Did you round the values to the nearest tenth?

Thanks for the video! There is one quick question, in ParaView GUI interface, the input parameter for gradient filter is scalar array, but it seems that field U is an array of vector (vx,vy,vz), how could we compute the gradient for it? Thanks!

Thank you for the tutorial :) When i run your cybetruck simple foam project i get following error: --> foam fatal error: invalid wall function specification. Patch type for patch topX must be wall. Current patch type is patch. Do you know the cause of this ? Thank you so much for the reply
@alexsfetcu9463 ай бұрын
edit: i found issue. Wrong boundary conditions, all types were selected as "patch". After correcting them to patch type "wall" and leaving only inlet and outlet as "patch" now simulation is running fine.

Hello, Autodesk Inventor is saving or exporting the assembly as a single .stl file with joined bodies. It is not giving separate stl file for each body for the assembly. What to do?
@akshay.kumar.k5 ай бұрын
Ok I got the answer, for anyone wondering. In "Save As", click options and them export as multiple files.
@gottagowork3 ай бұрын
If the file comes as one or you have multibody parts in one of the files that you want to animate separately, hit Tab in Blender to enter edit mode with the part selected, hit p key and "separate as loose parts". Be sure to set the origin point of each part, but sometimes (say on a piston arm) another point may be more relevant. If a part need multiple points of rotation, parent the part to an empty and animate the empty (both selected, then ctrl+p). Doing some Blender tutorials would be nice too. This guy don't seem to address some of the smoothing issues that may require some cleaning up of the imported geometry.

It can. If you do, you'll quickly learn why you shouldn't. Imagine a crash/blackout mid render that can take hours to days, or figuring out in the end the output settings were wrong. It's better to assemble the frames at the end, Blender can do this too.

As far as my understanding goes, the mesh you created in Ansys was a custom one. How did you get the 0, constant, and system files for the simulation to run? The rest of the video is very informative, so thanks.

Hi, just to ask, so it’s unlikely to convert Fluent mesh (one-cell-thick block mesh) in open foam as axisymmetric mesh (pie shape) am I right? I’ve done research and came out w the utility makeAxialMesh but it seems not able to use in openfoam? Correct me if I’m wrong.

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<Foam::wordRe>&, 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<Foam::wordRe>&, 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?
