The gradient of temperature is not a standard variable but it can be represented by a vector Additional Variable (AV) which is created in CFX-Pre. The components of the AV are defined as the components of the gradient, as shown in the excerpt of CCL below:

LIBRARY:
ADDITIONAL VARIABLE: GradT
Option = Definition
Tensor Type = VECTOR
Units = [K m^-1 ]
Variable Type = Unspecified
END
END
FLOW:
DOMAIN: MyDomain
FLUID MODELS:
ADDITIONAL VARIABLE: GradT
Option = Vector Algebraic Equation
Vector xValue = Temperature.Gradient X
Vector yValue = Temperature.Gradient Y
Vector zValue = Temperature.Gradient Z
END
END
END
END
