Summary0003429: interpolation scheme bug
Descriptionwhen the interpolationScheme is changed from "linear;" to "linear banana;" the solver didn't report a error.
it still run to finish.

Also when the interpolationScheme is changed to "linear QUICK" the results are the same.
Steps To Reproducecopy the scalarTransportFoam case from tutorials
change in system/fvSchemes file the interpolationScheme from "linear;" to "linear banana;"
run blockmesh and scalarTransportFoam

In the tutorials/basic/scalarTransportFoam/pitzDaily case if I change

divSchemes
{
    default none;
    div(phi,T) Gauss linearUpwind grad(T);
}

to

divSchemes
{
    default none;
    div(phi,T) bannana;
}

I get the error message

--> FOAM FATAL IO ERROR:
Unknown convection scheme bannana

Valid convection schemes are :

2
(
Gauss
bounded
)

if i replace the interpolation scheme with this "nonsense" line it still works, no error is reported

interpolationSchemes
{
    default linear Minmod linear;
}


or an another try with this configuration, the solver also did not report an error.

interpolationSchemes
{
    default linear banana;
}

What do you want scalarTransportFoam to interpolate using this scheme? Currently it does not interpolate anything using this scheme hence it generates no error when the scheme is nonsense.

i wanted to increase the accuracy of the solver and try benchmark it with different interpolations schemes.
e.g. this configuration works very well.
interpolationSchemes
{
    default cubic;
}

but for this test, the solver did not crash, and i don't understand this behaviour:

interpolationSchemes
{
    default linear banana;
}

 scalarTransportFoam does not use or need interpolationSchemes
