# Substitute to OpenFOAM's `changeDictionary`. Such tool is deprecated and the 
# use of `foamDictionary` is now encouraged. This function gets the direction of 
# the flow and changes the boundary file information.
#
# Input: $inflowDir
# Output: changes patch information in `constant/polyMesh/boundary` from `cyclic`
#         to `patch`
