Hello, I'm new here so I'm sorry if I'm in the wrong forum, if you can guide me it will be very good. Okay, I'm starting in OpenFoam and I've run the tutorial cases without much difficulty, but now I'm trying to run a particular case, where I will analyze the flow around a conical diffuser. I have the diffuser .stl file and would like to incorporate it into the control volume.

What I did: I copied the motorBike case and renamed and modified the files in the system folder, added the .stl file to the trisurface folder and configured the diffuser alignment on the control volume. After that, I executed the following commands:

surfaceFeatureExtract
blockMesh
decomposePar

so far without errors, so I ran:
mpirun -np 6 snappyHexMesh -overwrite -parallel

and he presented,

ERROR.txt

I don't know what I'm doing wrong, if any commands are missing. I await guidance and help

Hi,

Look at the error message - it tells you what is wrong.

"Point (3.0001 3.0001 0.43) is not inside the mesh or on a face or edge.
Bounding box of the mesh-0.5 -0.25 -0.25) (0.5 0.25 0.25)"

In your case, you changed the geometry (STL file) but you didn't change the locationInMesh point. You have set a point (3 3 0.43) as the locationInMesh point when your domain does not contain that point at all (and is smaller)

Adjust the locationInMesh point to something within your domain and you will not see this error.

Hope this helps.

Cheers,
Antimony
