Hi,
I have a boundary defined in boundary as:
inlets
{
type patch;
nFaces 0;
startFace 4555299;
}
I define for it a temperature condition as:
inlets
{
type fixedValue;
value uniform 383;
}

The problem is that after few iterations, the temperature field on the inlets is modified and the saved data looks like:
inlets
{
type fixedValue;
value nonuniform 0();
}
What does it mean "nonuniform 0()"?
How can I keep the temperature constant on the inlets?

It seems this situation is cha
 
It seems this situation is characteristic to a parallel computation.
I have all the inlets in a single partition and there I have the right temperature:
inlets
{
type fixedValue;
value uniform 383;
}

This is also the reason I have "nFaces 0" in all the processors except the one containing the inlets.

Quite simple!
