Hi Community,
I'm modelling a 3D rectangular simple geometry. The blockMesh command runs normally. However when I call in paraFoam command I get an error: ("Cannot find patchField entry for topWall") everytime after a few other trials too. I have 6 BC's in total for 6 faces as seen above.


Any help will be appreciated. Regards.

Hi Parth,


I had this error several times.


Each time, it was because I forgot to add a boundary condition in one of my physical variables (p, p_rgh, U, T...).
In your case, maybe you forgot to add a BC for topWall in one of your variables.


Or maybe you forgot to copy/paste a "variable.orig" to a "variable", if you use setFields.


Check the complete error message, it usually says which file is wrong.


If it is none of the above, maybe post the complete error message, it would permit people to help you better.



Regards,



Pierre
