Materials

  For the present analysis, you will model air as an incompressible fluid with a density of 1.225 kg/m $^3$ and a dynamic viscosity of 1.7894 $\times$10 $^{-5}$ kg/m-s. Since these are the default values, no change is required in the Create/Edit Materials dialog box.

1.   Retain the default properties for air.
