Hello guys,
Please has anyone been able to run snappyHexMesh on any foam-extend platform? I ran the same case on openFoam 5.x and foam-extend 4.0 and it works very smoothly on 5.x, however when I tried running the exact same case on foam-extend, i keep getting this error.

--> FOAM FATAL IO ERROR: 
keyword debug is undefined in dictionary "$WM_PROJECT_USER_DIR/FluidSolidInteraction/run/fsiFoam/Stanproj/system/snappyHexMeshDict"

file: "$WM_PROJECT_USER_DIR/FluidSolidInteraction/run/fsiFoam/Stanproj/system/snappyHexMeshDict from line 18 to line 310.

    From function dictionary::lookupEntry(const word&, bool, bool) const
    in file db/dictionary/dictionary.C at line 395.

FOAM exiting

Please can someone help with why I keep getting this error.

Thanks
Samuel

Have a look at snappyHexMeshDict examples in foam-extend. There most certainly be subtle differences in the dictionary entries of each version. Add the missing entries, which seems to be 'debug' in this particular example, and all will be well. :]

If the problem is more elaborate, you may first need to provide more complete picture of your problem. The following thread might give some insight regarding this: Guide: How to ask a question on the forums

Thank you that useful information. Specifically I am trying to carry out fsi simulations with fsiFoam based on real porous media image from mct scans. I used snappyHexMesh separately for both the fluid and solid cases.
Since I am simulating for solid deformation and fluid flow, I need both the solid and fluid domains coupled together. I tried to make both of them, inversions of the other hence giving them a common interface.
The fluidDomain.stl is the primary file. I got the solid by using the same exact snappyHexMeshDict file as the fluid and only changed the

locationInMesh

for the solid snappyHexMeshDict which worked out fine.
Hence solid boundaries are derived from the originally run blockMesh. The only problem I have now is that I need the interface of the solid whose boundaries are now hanging kind of hanging, in order to set the faceZones. i get this error when I run the setSet command for the solid.

I'm guessing that those are the interface points that are hanging without any specified name for them. My case folder is very huge therefore can't upload.
Attached is the image of both phases for fluid and solid. Please can you help me to map those interface points for the solid.

Thanks
