Dear foamers.
I want to try the schemes linearUpwind in interpolationSchemes for rhoCentralFoam solver.
In the begining my fvSchemes file looks so:

fluxScheme Tadmor;
ddtSchemes
{
default Euler;
}
gradSchemes
{
  default cellLimited leastSquares 1;
}
divSchemes
{
default none;
div(tauMC) Gauss linearUpwind;
div(phi,k) Gauss linearUpwind;
div(phi,omega) Gauss linearUpwind;
}
laplacianSchemes
{
default Gauss linear corrected;
}
interpolationSchemes
{
default linear;
reconstruct(rho) upwind;
reconstruct(U) upwind;
reconstruct(T) upwind;
}
snGradSchemes
{
default corrected;
}

Then i replace interpolationSchemes

interpolationSchemes
{
default linear;
reconstruct(rho) linearUpwind;
reconstruct(U) linearUpwind;
reconstruct(T) linearUpwind;
}

and OpenFoam gives out an error:

[3] --> FOAM FATAL IO ERROR: 
[3] Grad scheme not specified

Valid grad schemes are :

8
(
Gauss
cellLimited
cellMDLimited
extendedLeastSquares
faceLimited
faceMDLimited
fourth
leastSquares
)

Then i replace interpolationSchemes to

interpolationSchemes
{
default linear;
reconstruct(rho) Gauss linearUpwind;
reconstruct(U) Gauss linearUpwind;
reconstruct(T) Gauss linearUpwind;
}

OpenFoam gives out an error:

[17] --> FOAM FATAL IO ERROR: 
[17] Unknown discretisation scheme Gauss

Valid schemes are :

51

How probably to use linearUpwind?

Thanks.
