Hello,
I have started learning OpenFOAM recently, for my thesis work, and I'm also new to CFD. Basically, I'm trying to analyze the flow dynamics of an open channel in the presence of obstructions (such as wooden debris and vegetation). But I'm stuck with an error "Cannot find patchField entry for Inlet".
I have been trying to solve this error, but I'm unable to do so. I came across this thread while searching for a solution.
I am posting the error which I got after running interFoam.


--> FOAM FATAL IO ERROR:
Cannot find patchField entry for Inlet
