Parts of my code read as:

volScalarField h
(
IOobject
(
"h",
runTime.timeName(),
mesh,
IOobject::MUST_READ,
IOobject::AUTO_WRITE
),
mesh
);

-------------------------------------------------------------
fvScalarMatrix h_Eqn
(
(rho_frac*F)*fvm::ddt(h)
==
fvm::laplacian(Ku,h)
+
rho_frac*grad_Kuz
+
rhoC_frac*q
);

h_Eqn.relax();
h_Eqn.solve();

-------------------------------------------------------------
Now after solving for h, I need to reassign the values of h before it passes on to the next time-step. The values of the h field which are having values less than -1 are to be set to -1. This modified h field has to be passed on the next time step.

How to accomplish this?
