Symmetry boundary condition in a heating pipe
Hello! Me and a friend are solving an example from Victor's Pozzobon tutorials, example 8 to be specific and we are having troubles setting the 'symmetry' boundary condition, when we set it in the Temperature file like this:
Code:
FoamFile
{
version 2.0;
format ascii;
class volScalarField;
object p;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //
dimensions [0 0 0 1 0 0 0];
internalField uniform 20;
boundaryField
{
inlet
{
type fixedValue;
value uniform 20;
}
outlet
{
type zeroGradient;
}
wall
{
type convectiveHeatFlux;
}
axis
{
type symmetry;
}
back
{
type wedge;
}
front
{
type wedge;
}
}
// ************************************************************************* //
We keep getting this message after running the solver:

What can we do to solve the error?
Many Thanks! |
