The EngineerDo provided the most helpful tutorials in topics related to CFD and CFD-DEM. Thanks.

Super video. Ich hatte mich bisher noch gar nicht mit einer Foam-GUI befasst. Sollte aber ein tolles Tool sein um "Anfängern" und Leuten, die an GUI-Programme gewöhnt sind, den Einstieg zu erleichtern.
Übrigens: mit den neueren Blender Varianten kann man alle Objekte auf einmal als *stls exportieren lassen indem man bei "batch mode" -> object wählt. Wenn man beim exportieren den Namen weglässt, dann übernimmt er einfach den Namen des Objekts und macht daraus "objektName.stl" :)

Great video. I hadn't looked into foam-GUIs yet, but I think they should really help "beginners" and anyone who makes the transition from other GUI based applications.
In addition: The newer Blender versions allow to export all objects in separate *stls via ONE-click by choosing "object" as batch mode when exporting the *stl. Furthermore, when you leave the name field of the exported file empty, it will automatically create the name "object_name".stl

Thank you very much, sir! It's very helpful.

Richtig gut Meister. Deine Videos gefallen mir, weiter so!

Thanks for the video. Lot of useful info.

Thank you very much EngineerDo for your very clear and explanatory videos. I would like to know if Seimens NX can be used for both CAD modeling and meshing?

[Kurosaka]

Dank ye, grazie, and شكرا for your work

Congratulations, it is a very good tutorial. Can you provide some help for installing OpenFoam and Helyx-OS?

[markoj]

As a semi professional cfd user, the mesh is good enough for demonstrations.

Do you benchmark your simulation with experimental or numerical data?

Because the mesh should be aligned with the flow as much as possible. If not, false (numerical) cross diffusion is introduced.

But as I wrote for demonstrations your guide is perfect.

Hi Engineerdo, I'm using OpenFOAM-v2112 and recently I download Helyx-OS-2.4.0-Linux. Can you make a quick tutorial on how to install helix and run OpenFOAM on it? Thanks! your videos are very helpful. Love it!

[danielb.]

Danke für das Tutorial. Kann ich damit auch den Verguss von Resin bei Unterdruck simulieren? Also höhere Viskosität, Newton und Luft bei Unterdruck.

Hi! I got this message:

--> FOAM FATAL ERROR:
[1] Solution convergence criteria specified in PIMPLE.residualControl must be given as single values. Corrector loop convergence criteria, if appropriate, are specified as dictionaries in

When I try to change the residual control settings, everything comes back to the previous situation when I press "run"

Do you know how to solve this?
Thanks!

[Ardenffffff]

Hi there, thanks for the video. After I click to run, I have the error msg saying that process exited with an error: 1 (Exit value: 1). Any ideas? Many thanks

Dear Friend, is possible include in helyx os a momentum source for a vehiculator fan? put the cylinder and set up the momentum source? :)

[bekish]

Hello, thanks for the video it was very interesting, but I would like to know if it is possible to add my own turbulence model?

[jaa]

Sir, what is the dimensions of the pipe? Where do you set it up? And which units? centimeters? inches?

[shuvashishroy]

how can i assign suction boundary in the outlets? Thanks.

[AndreLuiz-dzqk]

Someone can help me? I got this message 3 times:
FOAM FATAL ERROR:
[3] Solution convergence criteria specified in PIMPLE.residualControl must be given as single values. Corrector loop convergence criteria, if appropriate, are specified as dictionaries in

Thanks guys!!

Why not close all the ends of the pipe off and label the inlet, outlets, and walls in SolidWorks?

Gibt es einen Weg, helyx und Openfoam 10 zu nutzen? Ich habe das Problem, dass Openfoam kein Mesh findet, wenn ich auf Exportieren drücke. Es kommen nur Fehlermeldungen.
