Its exact define is:
Code:
    volScalarField rhok
    (
        IOobject
        (
            "rhok",
            runTime.timeName(),
            mesh
        ),
        1.0 - beta*(T - TRef)
    );
for more information see the Incropera's Introduction Heat Transfer, chapter 9.

Click on the calculator button and define a Result Array Name rhok


1-beta*(T-Tref)


eg in my case 1-3e-03*(T-275.74)


Should be fine
