STAR-CCM+ NACA 4412 Airfoil Tutorial and Turbulence Study/Validation with NASA Results (2020)
HTML-код
- Опубликовано: 6 июл 2024
- Here's a slightly different video using Siemens Star-CCM+ for a NACA 4412 Turbulence Study. While I still prefer ANSYS Fluent and Star-CCM+ isn't as popular as ANSYS, but STAR-CCM+ definitely has a few advantages, mainly in meshing and arguably in its overall streamlining. Hopefully this can help some people if they ever get around to use its capabilities.

Hey,
You just saved me from getting a low grade on a project of mine.
Amazing tutorial. Keep up the good work.
Cheers
Thank you for providing this very informative & easy to follow tutorial! was able to get some initial results for a project based off of your work so thanks for taking the time out :)
Really good tutorial Anthony. Thank you very much!
Great tutorial - very alive and informative :>
Any chance you could share that paper you've been referring to and showing time to time?
awesome tutorial buddy!
Could you please provide the journal paper if you don't mind, as I am working on something really similar so it would be immensely useful to me!
Great job and nice video!
Just a few tips. The mesher gets the boundary settings (like Prism Layer on the walls) from boundaries from Region, so you should set correct type of your boundaries in Region first before start meshing. And, maybe your would not need to add additional custom controls then. Next, you can set initial velocity in the whole domain in Continua - Physics - Initial Conditions node. It will decrease the convergence time. Next one, you can create a custom local coordinate system in Tools - Coordinate Systems - Laboratory - Local Coordinate Systems and set it as Reference System whereve you set the velocity values. Then you can rotate this CS by right click on it and change the angle of the flow thought all model by few clicks.
Привет Дима, не подскажите где можно найти хорошую литературу или обучалки для моделирования турбулентности на Star ccm+? Спасибо заранее
@@bekish9679 Мне внятной литературы по Star-CCM++ так и не попадалось. Так что лучшее - это сама справка по Star-CCM, благо там очень много материала. А вообще матмодели практически во всех CFD пакетах одни и те же, так что можно посмотреть параметры настроек для турбулентных течений в материалах по, например, ANSYS (их более, чем достаточно на просторах). Либо, если хочется доступно и на русском, можно скачать справку по FlowVision (вроде она доступна для скачивания на официальном сайте). Там довольно неплохо расписано.
@@stealth-350 хорошо спасибо
Hey, great video man, helped me out a lot on my project. Would love to read the technical paper that you showed in the video, is there any way I can do that?
Greatly step by step explained and
highly beneficial to know how to interact with ui.
Still, how did you selected the FACE? (which is then named as INLET)
when I try to select the face , whole BODY is getting selected.
Is there any criteria for a FACE to be selected??
nice tutorial! is there some tutorial for the simulation u have opened titled "star 1"? i need a trimmed mesh of a rotating domain and i think your file is about this. thank you!
Dear can you please share the paper you are showing because i am doing my project based on find out suitable turbulence model using ansys
I like the way you pronounce 'Polygonal'. Cheers mate !
how you are able to select only side of face for upper and fluid domain?
It's a nice tutorial. I am curious on what criteria you define how many prism layers you need? I know the overall prism thickness should correspond to boundary layer thickness.
the most important is the first to ensure the y+ value < 1 for the viscous sublayers and generally you want at least 10 layers with 1.2 growth rate or less. There's mesh studies that look into this but yes you generally want the boundary layer to be well resolved.
when i download the coordinates all coordinates stuck in one colomn its so annoying idk how to fix?
I actually did exactly the same, but it says: unable to import input.csv file.. do you have any suggestion?
that format should work, so maybe check to make sure you don't have any random values somewhere else in the file
Osum!
