Hi,
I have a script for fvSchemes file and the fvSchemes and fvsolutions files have defined all the solvers.



This is my fvSchemes file.
FoamFile
{
version 2.0;
format ascii;
class dictionary;
location "system/fin";
object fvSchemes;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

ddtSchemes
{
default steadyState;
}

gradSchemes
{
default Gauss linear;
}

divSchemes
{
default none;
}

laplacianSchemes
{
default none;
laplacian(alpha,e) Gauss linear corrected;
}

interpolationSchemes
{
default linear;
}

snGradSchemes
{
default corrected;
}

// ****************

and this is my fvsolution file.

FoamFile
{
version 2.0;
format ascii;
class dictionary;
location "system/fin";
object fvSolution;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

solvers
{
"e.*"
{
solver GAMG;
smoother symGaussSeidel;
tolerance 1e-6;
relTol 0.1;
}

// eFinal
//{
// $e;
// tolerance 1e-06;
// relTol 0;
//}

"alpha.*"
{
solver GAMG;
smoother symGaussSeidel;
tolerance 1e-6;
relTol 0.1;
}


}

PIMPLE
{
nNonOrthogonalCorrectors 0;
}

relaxationFactors
{
equations
{
e 0.7;
alpha 0.7;
}
}

However, when I run my program using chtMultiRegionFoam solver, always there is an error and the error can be described as follows.
Solving for solid region fin


--> FOAM FATAL IO ERROR:

I tried to change the key word alpha to alphae too. however, when I did like that way the terminal crashed. I checked all my boundary conditions in both fin and air too. But still struggling with the error. Therefore, could you please help me to solve this.Is that the error with memory?
