Greetings OpenFOAM community,I've encountered an error that's left me a bit stumped. I've been working on adapting a simulation from a motorBike case to a new geometry, specifically an F1 rear wing, for simplicity's sake. However, I only changed the name of the new geometry while keeping the internal structure the same as motorBike.
Despite only renaming the new geometry without altering the internal structure, I'm facing the persistent error message "Cannot find patchField entry for motorBike" when running the simulation.
Is there a specific file or setting within OpenFOAM where the reference to the motorBike case might still be lingering, causing this error? I haven't modified any other settings except for the name change of the new geometry, the blockMeshDict and some things of the snappyHexMeshDict.
I'd greatly appreciate any insights or suggestions on how to resolve this issue. Thank you!

This is the error message:

Hello,

What do you see in your constant/polyMesh/boundary file? (or processor*/constant/polyMesh/boundary if you're running in parallel)

Yes, this is it the processor*/constatn/polyMesh/boundary:

And i forgot to write it, but the step im following are the same (without the importing part), of the Allrun file:

#!/bin/sh
cd ${0%/*} || exit 1    # Run from this directory

# Source tutorial run functions
. $WM_PROJECT_DIR/bin/tools/RunFunctions


runApplication blockMesh
runApplication decomposePar -copyZero
runParallel snappyHexMesh -overwrite

find . -type f -iname "*level*" -exec rm {} \;

runParallel renumberMesh -overwrite

runParallel potentialFoam -initialiseUBCs

runParallel $(getApplication)

Alright, in the boundary file you have a patch named motorBike but in your boundary conditions you are defining conditions for every patches starting with motorBike_

So the solver complains because it cannot find a boundary condition for the patch motorBike

Update your files in 0 directory with motorBike (match only the patch named motorBike) or "motorBike.*" (matches any patches starting with motorBike) instead of "motorBike_.*"

Omg, that worked, you helped me a lot, thanks
