the figure with the fluid properties and flow conditions. The
problem has analytical solution so that the computed solution can
be compared. The shock wave angle  is determined from the
transcendental function,

We will employ Fluent in ANSYS through its Workbench to solve
for the flow behavior.

(a) Starting ANSYS Workbench

 Open the ANSYS Workbench, set the Units menu on the

upper tab to Metric (kg,m,s, C,A,N,V).
 On the Analysis Systems window, click twice on the Fluid
Flow (Fluent) item. A new small box will appear on the
Project Schematic window.
 Retype the name in the lower blue tab as the desired project
name, e.g., Mach 3 Flow over Wedge, and hit Enter.
 Right click on the Geometry tab and select the Properties
option, the Properties of Schematic window will open.
Change the Analysis Type under the Advanced Geometry
Options from 3D to 2D. Then, close this window.
 Back to the Project Schematic window, right click on the
Geometry tab and select the New Geometry…. This will
launch the ANSYS Design Modeler (green logo DM).
