I'm currently using a Boundary Condition similar to FixedValue(faces=mesh.getFacesRight(),Value), FixedValue(faces=mesh.getFacesLeft(),Value2)...

To satisfy a boundary of Jq*n=0  ,  T|x=0 = Value,  T|x=L = Value2

I would say that those should be FixedValue(faces=mesh.getFacesLeft(),Value), FixedValue(faces=mesh.getFacesRight(),Value2), as x increases from left to right.

Also, the default no-flux boundary condition Jq*n=0 applies to faces *other* than x=0 and x=L. You can't impose both zero flux and fixed value on the same boundary.
