Setting Boundary Conditions and Values

Set the physical conditions at the domain boundaries.

The geometry for this tutorial has only two boundaries:
  • A wall boundary representing the surface of the airfoil.
  • A free-stream boundary at the external edge of the solution domain.
  1. Rename the Regions > Default_Fluid 2D node to Fluid.
  2. Select the Fluid > Boundaries > freestream > Physics Conditions > Flow Direction Specification node and set the Method property to Components.
  3. Edit the Physics Values node and set the following properties:
    Node Property Value
    Flow Direction Coordinate System Laboratory - > Cartesian 1
    Mach Number Value 0.725
    Static Temperature Value 300 K
  4. Save the simulation.
