To what extent is not not right? Is it off by a little or is it completely
wrong? I ask, because in your original email, you said

but the code you sent had
UpBC = FixedValue(faces=maskUpSurface, value= Tair)
LowBC = FixedValue(faces=maskLowerSurface, value= Tair)

The next release has support for quadrangles and hexahedrons.
