    - Prerequisites
      The instructions in the Simple Java Macros tutorial assume that you are already familiar with certain techniques in Simcenter STAR-CCM+.
    - Importing the Volume Mesh
      To set up the Simcenter STAR-CCM+ simulation, launch a simulation and import the supplied volume mesh.
    - Converting the Mesh to Two-Dimensions
      Simcenter STAR-CCM+ can use the surface of a three-dimensional mesh to create a two-dimensional mesh if the surface to be used lies on the X-Y plane at Z = 0.
    - Selecting the Physics Models
      Physics models define the physical variables and phenomena in the simulation. An incompressible isothermal turbulent flow is sufficient for this analysis. Use the segregated flow model with the k-omega turbulence model.
    - Setting Boundary Conditions and Values
      Specify a constant velocity in the X direction at the inlet, and a constant pressure at the outlet. Set the centerline boundary to be of type axis. This axis boundary must lie exactly on the Y = 0 line; project the axis to the appropriate plane.
    - Setting Stopping Criteria
      Set the stopping criteria for the simulation. By default, simulations are set to stop after 1000 iterations.
    - Visualizing the Simulation
      Create a scalar scene to display the pressure field as the solution develops.
    - Running the Simulation

Setting Stopping Criteria

Set the stopping criteria for the simulation. By default, simulations are set to stop after 1000 iterations.

In this simulation, convergence is reached before then, so reduce the maximum number of iterations to 600.

Select the Stopping Criteria > Maximum Steps node and set Maximum Steps to 600.
Save the simulation.
