Hello all,

I am new to OpenFoam and I'm trying to solve a simple (at last I think it is...) case in which I have a heated rod inside a pipe. For natural convection it seems ok.

When I try to start a flow (inlet and outlet flows) I get a "continuity error message".

I based the configuration files on "hotRoom" OpenFoam's tutorial case.

The boundary conditions are:

p: inlet -> zeroGradient
outlet -> FixedValue uniform 0;
insideWall -> zeroGradient;
outsideWall -> zeroGradient;

U: inlet -> FixedValue (0 1 0)
outlet -> ZeroGradient (or calculated $internalField;
insideWall -> FixedValue (0 0 0);
outsideWall -> FixedValue (0 0 0);

T: inlet -> FixedValue 300;
outlet -> zeroGradient (or calculated $internalField);
insideWall -> FixedValue 1000;
outsideWall -> FixedValue 300;

So, any suggestions?
Thanks in advance.
