Hi I am getting this error

wrong token type - expected Scalar, found on line 0 the word 'nan'

file: C:/OpenFOAM/cygwin64/home/mahaanu/OpenFOAM/mahaanu-2.3.x/run/trial_plate2/system/data.solverPerformance.p_rgh at line 0.

From function operator>>(Istream&, Scalar&)
in file lnInclude/Scalar.C at line 93.


I am trying to solve a porousInterFoam problem with the following boundary conditions for resin as the fluid. Can you please tell me where I am going wrong?

Thanks in advance!

P_rgh
boundaryField
{
FrontAndBack
{
type empty;
}

atmosphere
{
type totalPressure;
p0 uniform 0;
U U;
phi phi;
rho rho;
psi none;
gamma 1;
value uniform 0;
}

lowerWall
{
type fixedFluxPressure;
value uniform 0;
}

leftWall
{
type fixedFluxPressure;
value uniform 0;
}

rightWall
{
type fixedFluxPressure;
value uniform 0;
}

porosityWall
{
type fixedFluxPressure;
value uniform 0;
}


}

}

atmosphere
{

}

lowerWall

value uniform (0. 0. 0.);
}

leftWall

}

rightWall

}

}


}

{
type zeroGradient;
}

rightWall
{

}

lowerWall
{

}

porosityWall

}

atmosphere
{

}

}

Hi,

I am no expert, but looking at your error message and trying to decode it:

1) "nan" is usually "Not a number" and is not a good thing
2) I have never seen a case structure with "system/data.solverPerformance.p_rgh" (but this may be due to my inexperience)

You did not give very much info, some follow up questions:
1) When do you get this error? As you run the case? After some iterations?
2) What files do you have in your "system" folder in your case setup?
