            analysis of the air flow passing through a truck. Assume air at room temperature of 25°C
            for the flow field with an air velocity of 40 km/hr blowing from left to right. Use non-slip
            boundary conditions along the walls of the truck and the ground surface. Find the airflow
            pattern as well as the pressure and velocity distributions of the flow field around the truck.

                                                        is 1.6 m wide, and each wheel is 0.2 m wide.
              Flow field: Incompressible air at 25°C.
              Boundary conditions: Air is blowing from left to right at a velocity of 40 km/h.
              Nonslip boundaries along the walls of the truck and the ground surface.

                   Step 1: Start an ANSYS Workbench Project
                   Launch ANSYS Workbench and save the blank project as ‘CFD_Truck.wbpj’.
                   Step 2: Create a Fluid Flow (CFX) Analysis System
                   Drag the Fluid Flow (CFX) icon from the Analysis Systems Toolbox window and
                     drop it inside the highlighted green rectangle in the Project Schematic window.
