I am trying to run the example of motor bike , when I ran surfaceFeatureExtract command i am getting below error

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

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

FOAM exiting

Hi,



i just checked the tutorial and you might have forgotten to run "Allrun".

The error occurs because there is no file "motorBike.obj".

It should be in the folder constant/trisurface.
You can copy it manually from $FOAM_TUTORIALS/resources/geometry or via the "Allrun" Script. You will find this information in the constant/trisurface folder in the README.

Thanks for the suggestion i am able run it ,but i modified the tri surface folder file with cylinder part which is saved in Ascii

I tried both .stl and STL still same error


Note: Feature line extraction only valid on closed manifold surfaces

Reading surfaceFeatureExtractDict

It's hard to find the error without seeing your files.

It might be a problem with the edited geometry or you just forgot to change the surfacefeatureextract file?


how did you edit the geometry? Did you check the geometry? You can open the stl in Paraview.


Did your blockmesh run properly?

As FDStoFOAM said, please check that the files are correctly positioned within the case. Its probably just at the wrong location.

I don't exactly understand how you edited the geometry.
It might be a problem with your STL or you just didn't change a file that you should have changed.
Is your blockmesh right?

Did you edit the surfacefeatureextractdict as well after changing the geometry?

Is your geometry in the right folder?

There are many possibilities.
