8.5.1 Constant Thermal Conductivity

If you want to define the thermal conductivity as a constant , check that constant is selected in the drop-down list to the right of Thermal Conductivity in the Create/Edit Materials dialog box (Figure  8.5.1), and enter the value of thermal conductivity for the material.

For the default fluid (air), the thermal conductivity is 0.0242 W/m-K.
