Setting Boundary Conditions

Define the boundary conditions for the thermal analysis.

  1. To set the mass flow rate and the temperature of the gas at the inlets:
    1. Edit the Regions > Exhaust Gas > Boundaries > Inlets > Physics Values node and set the following properties:
      Node Property Setting
      Mass Flow Rate Value 0.05 kg/s
      Total Temperature Value 450 C
  2. Set the boundary conditions for the fluid region:
    1. Edit the Regions > Fluid > Boundaries > Inlet > Physics Values node and set the following properties:
      Node Property Setting
      Static Temperature Value 25.0 C
      Velocity Magnitude Value 1.0 m/s
    2. Edit the Regions > Fluid > Boundaries > Outlet > Physics Values > Static Temperature node and set Value to 25.0 C.
  3. Save the simulation.
