Hi,
I start to learn OpenFOAM and try to make my own mesh for T pipe inside icofoam tutorial case. I would very thankful if somebody can describe how to deal with errors that I have in log file. CheckMesh says that mesh is OK. The pressure and velocity b.c. seem to be consistent:
U
"internalField uniform (0 0 0);

boundaryField
{
inlet_F
{
type fixedValue;
value uniform (0.1 0 0);
}

outlet_F1
{
type zeroGradient;
}

outlet_F2
{
type zeroGradient;
}

pipe
{
type fixedvalue;
value uniform (0 0 0);
}
}"
P
"internalField uniform 0;

boundaryField
{
inlet_F
{
type zeroGradient;
}

outlet_F1
{
type fixedvalue;
value uniform 0;
}

outlet_F2
{
type fixedvalue;
value uniform 0;
}

pipe
{
type zeroGradient;
}

}"
I use default fvSchemes and fvSolution files.

Log file contains the following info:

"Create time

Create mesh for time = 0

Reading transportProperties

Reading field p

Reading field U

Reading/calculating face flux field phi


Starting time loop

Time = 0.001

Courant Number mean: 0 max: 0


--> FOAM FATAL ERROR : gradientInternalCoeffs cannot be called for a defaultFvPatchField.
(Actual type fixedvalue)
You are probably trying to solve for a field with a default boundary conditions.

From function defaultFvPatchField<type>::gradientInternalCoeffs( ) const
in file fields/fvPatchFields/basicFvPatchFields/default/defaultFvPatchField.C at line 489.

FOAM exiting"
The same errors are for the same mesh and b.c.even in potentialfoam

Thanks,
Sergey.
