Hi friends

I'm trying to make .emesh file from my .stl file for snappyHesh. but when I apply the command: srfaceFeatureExtract,this happens:
FOAM FATAL ERROR:
Cannnot read "surface.stl"

From function triSurface::read(const fileName&, const word&, const bool)
in file triSurface/triSurface.C at line 369.
can you give a comment about it?

Many thanks

Dear Reza

you might saved your STL file in binary format , so i guess if you save it in ASCII format, then error would be solved

[gooya_kabir]

would you help me how to change .stl to binary one?
I tried autocad, but it didnt work

[nimasam]

Open your STL file in paraview and save in in STL format ASCII one

Hi Sam,

Thank you for your help, I saved the file in Ascii format and run it again, but the same error appeared:

What do you think????

thanks

[nimasam]

i have no idea, you may want to post your test case here, then OpenFOAM users can help you

[gooya_kabir]

Hi friends,

As I told my problem, I could not use surfacefeature extract and above message come to my terminal after run. I tried with many cases and I got the same result!!! I uploaded one of the stl files. If you can see that what's the problem, it would be a great help for me.

Thank you in advance

[nimasam]

did you edit your surfaceFeatureExtractDict at all?
However, it works for me , i used OF-2.2.0, and i add working test case with your stl file

to use following test case:

1- open zip file
2- run script

./preAllrun

[gooya_kabir]

Many thanks for your help. As you helped me I could solve the problem. In my case, OF could not find the directory but it showed an error about not being able to read the file. I change the path and it work.
Now I generate the mesh, but since the surface structure is complicated, I do not know how to define the boundary (Wall type) on the surface. Is there any feature which help me to define the boundary on the surface?

Hi all,

I am trying to use the surfaceFeatureExtract in the motorBike (OpenFOAM-v3.0+) tutorial case; however it is not working. It always says "command not found".

Do you know if the surfaceFeatureExtract still in use in OpenFOAM-v3.0+ ? How to solve this problem ?

Thanks.

[maryCFD]

Hi Rophys,

I can assure you that surfaceFeatureExtract still works in OpenFOAM-v3.0+.
But I don't know what is wrong with it in your case. Can you post more details ? Are you sure of your installation ?

Hi Mary,

Thanks for that. I already solved the problem =)

Cheers,

Hi,

I have also the same problem with command surfaceFeatureExtract, and got message command not found, on OpenFOAM-v3.0+.

What to do?

Thanks

[JulienS]

Hi all,

I also have the problem with "command not find". My installation looks correct, solvers work fine apart of that.
Rophys, how did you solve the problem?

Best regards

Julien

I am having this same issue with 3.0+. Considering rolling back to a previous version, but if it is assured to work then I am not sure how to fix the problem.

I have also the same problem with command surfaceFeatureExtract, and got message command not found, on OpenFOAM4.0.

Please tell me how to solve it.

Thanks

I solved the issue by removing the installation and installed it again. Now works.

[zxzx]

Thanks, I did it too. Now it works
