When you record a journal file of an operation that uses CFX-Pre, the contents will be similar to the following code snippets. In these snippets, a user has opened Workbench and recorded a session that created a CFX system, opened CFX-Pre, imported a mesh file (SYS-1.cmdb), created an inlet boundary, created an outlet boundary, and saved the project as saveJou.wbpj:

In the above snippets, note how CCL and command actions for CFX-Pre are encapsulated as arguments of SendCommand instructions.

When you record a journal file that refreshes and updates a CFX Solution cell, the contents will be similar to the following snippet.

RefreshComponent(Component="/Schematic/Cell:Solution")
UpdateComponent(
    Component="/Schematic/Cell:Solution",
    AllDependencies=True,
    Force=False)

In the following incomplete snippet, a user has created a Results system, edited the Results cell, loaded a CFX-Solver Results file (StaticMixer_001.res) and then created a plane named "Plane 1":

The commands in the script above are the default values for a plane.

If you have a Workbench project currently open, you can run a script to change the characteristics of the simulation. For example, if you have edited a Setup cell from a Workbench system, loaded a case with a Default Domain in Flow Analysis 1, and want to use an interactive script to set CFX-Pre to use one of two turbulence settings, you can run a script similar to the one that follows.

Before running this script, you would have to first open the Command Window dialog box (by selecting File > Scripting > Open Command Window from the Workbench main menu). To run the script, you would select File > Scripting > Run Script File from the Workbench main menu and then use the browser to open the file containing the script.

x = int(raw_input("Enter: 1=k epsilon, 2=Shear Stress Transport (SST): "))

if x == 1:
	print 'k epsilon'
	SetScriptVersion(Version="12.1")
	system1 = GetSystem(Name="CFX")
	setup1 = system1.GetContainer(ComponentName="Setup")
	setup1.Edit()
	setup1.SendCommand(Command="""FLOW: Flow Analysis 1
	DOMAIN: Default Domain
	    FLUID MODELS: 
	      TURBULENCE MODEL: 
	        Option = k epsilon
	      END # TURBULENCE MODEL:
	      TURBULENT WALL FUNCTIONS: 
	        Option = Scalable
	      END # TURBULENT WALL FUNCTIONS:
	    END # FLUID MODELS:
	  END # DOMAIN:Default Domain
	END # FLOW:Flow Analysis 1""")

elif x == 2:
	print 'Shear Stress Transport (SST)'
	SetScriptVersion(Version="12.1")
	system1 = GetSystem(Name="CFX")
	setup1 = system1.GetContainer(ComponentName="Setup")
	setup1.Edit()
	setup1.SendCommand(Command="""FLOW: Flow Analysis 1
	DOMAIN: Default Domain
	    FLUID MODELS: 
	      TURBULENCE MODEL: 
	        Option = SST
	      END # TURBULENCE MODEL:
	      TURBULENT WALL FUNCTIONS: 
	        Option = Automatic
	      END # TURBULENT WALL FUNCTIONS:
	    END # FLUID MODELS:
	  END # DOMAIN:Default Domain
	END # FLOW:Flow Analysis 1""")

print 'Done'

Depending on the value of x you input in the Command Window, the script includes the CCL in the appropriate setup1.SendCommand argument to set the TURBULENCE MODEL and TURBULENT WALL FUNCTIONS options in the FLOW: Flow Analysis 1 > DOMAIN: Default Domain > FLUID MODELS object for either the k-Epsilon or the Shear Stress Transport turbulence models.

If you have a Workbench project currently open, you can run a script to change how the results of the simulation are post-processed. For example, if you have edited a Results cell from a Workbench system and CFD-Post is displaying a plane named Plane 1, you can run the following script to change the plane to be colored by the variable Velocity or Pressure:

x = int(raw_input("Enter an integer: 1=Velocity, 2=Pressure: "))

if x == 1:
		print 'Velocity'
		results1.SendCommand(Command="""PLANE:Plane 1
		Colour Mode = Variable
		Colour Variable = 'Velocity'
		END""")

elif x == 2:
		print 'Pressure'
		results1.SendCommand(Command="""PLANE:Plane 1
		Colour Mode = Variable
		Colour Variable = Pressure
		END""")

Depending on the value of x you input, the script includes the CCL in the appropriate results1.SendCommand argument to set the values for Colour Mode and Colour Variable in the PLANE:Plane 1 object for either the Velocity or Pressure variable.
