Open Foam Tutorial: Simulation with 3D Geometry (.stl)

LINK TO FILES USED IN TUTORIAL:

This tutorial goes through a k-omega model with your own imported geometry (or, feel free to use the 3D geometry that is already in the folder!)

This is an easy, adjustable way to set up a simulation for your own 3D geometry and view results.

Excellent ! Excellent ! Very impressive, clear and complete tutorial to introduce to snappyHexMesh. I searched a hole day for a good one without success. Thank you and I hope you will continue to help OpenFoam community.

Wow, so structured and well explained. Thank you for sharing your knowledge!

[Filipcorobivblenderi]

I think, we need more tutorials like this

[johnnyzhang]

Thank you! That is one of the best and simplest tutorials ever in YB. This one is really helpful to solve some simple geometry cases, thanks again!

[dabarney]

Perfect length, perfect depth in a well structured form. Thank you Lily for the best 3D openFOAM beginner tutorial so far.

[Akshayoes]

Very informative and thanks for all the ques posted and received answers

[igor_shepelev]

Thanks a lot! Just a couple of issues in preGeo folder files. 1) > cylinder.stl 2) 0\omega - add closing bracket at line 49.

[whosthisguythinkheis]

probably the easiest OpenFOAM tutorial to follow on YT, Thankyou so much!

[nowsee]

thank you very much, this is the best video about snappyhexmesh of openFOAM, looking forward more videos about it .thanks again!

Thank you for the tutorial! I've a question about running surfacemeshextract. When i try to run this code, i got an error says: surfaceFeatureExtract
surfaceFeatureExtract: symbol lookup error: surfaceFeatureExtract: undefined symbol:

I've been searching for a solution for the problem but i've got nothing, do you have any idea what this is about?

[eastonpal]

Excellent tutorial! It seems like the vertices' coordinates in blockMeshDict have the z-coordinate in the opposite direction from the diagram you drew @2:37. Why is that?

[manjunathshastry]

Hello, I am getting this error. Could you please help me.


Reading surfaceFeatureExtractDict



--> FOAM FATAL ERROR: (openfoam-2012)
No surfaces specified/found for entry: cylinder.stl

From int main(int, char**)
in file surfaceFeatureExtract.C at line 305.

I'm stuck here :( . I even checked whether the cylinder file is in ascii format or binary. I saved it again in ascii format, but it still gives me the same error. Could you please let me know what to do.

How did you get the quick command to show up in after you right clikced? :)

[thatnicebee]

if i have different dimension of geometry, can i have to change it on 0 folder?

[hackernik]

But how do you create the blockMeshDict file? I just don't understand that part

[dannydanny]

thank you, the cylinder works fine! I've tried to change the cylinder with my stl but I got some problems: my stl is a naca64 split in half simetrically but the simplefoam seems to compute the pressure only in the left half, so when I compute lateral thrust and drag with Paraview I get unconsistent results. Why this happens? Can you help me?

[docd]

Nice - big thanks, nice template for further exploring OF.

[FoolishGamerYT]

i followed her instruction but the blockmesh doesn't run on the PC, why is that?

[gilverrosero]

Hello
Thank you for the video. There is valuable information but i have an issue into my terminal when i run surfaceFeatureExtract into preGeo. This says: bash: surfaceFeatureExtract: command not found.


why is this error?

Thank you for the information that you can give me!

[rahulnair]

can i perform this tutorial with other geometry?? I am trying but its not excecuting surfaceFeatureExtract step
