Control Panel Run Introduction
The Run panel enables you to control the CFD-ACE-Solver and monitor the simulation while it is running. The Run panel is shown below.

Control Panel Run-Parallel Run
The Parallel Run option activates parallel processing of the simulation from CFD-ACE-GUI. For more information, see Parallel Processing.
Control Panel
Run-Submit to Solver
The Submit to Solver function launches the CFD-ACE-Solver for the current simulation. If no changes have been made to the simulation settings, then the solver will start immediately. If changes have been made to the settings, the Submit window appears.
Submit Window
Because the simulation data has been modified, the DTF file must be updated before it is passed to the CFD-ACE-Solver. Press the Submit Job Under Current Name button to save the data to the current DTF file and launch the solver. Press Submit Job Under a Different Name to save all of the simulation data to a new DTF file and then launch the solver. The Cancel button cancels the operation and the job will not be submitted.
Control Panel
Run-Parametric Run with SimManager
The Parametric Run with SimManager button saves the DTF file and launches the SimManager program in the Parametric Wizard mode. The appropriate file settings will be made so that setup of a parametric SimManager run can be quickly made for the simulation.
Control Panel
Run-Optimization Run with SimManager
The Optimization Run with SimManager button saves the DTF file and launches the SimManager program in the Optimization Wizard mode. The appropriate file settings will be made so that setup of an optimization SimManager run can be quickly made for this simulation.
Run-View Residuals
Control Panel
Run-View Residuals Introduction
Once the CFD-ACE-SOLVER job has been submitted and the solver starts to write the residual history file (modelname.RSL), the View Residuals function becomes active. The function will also be active if a modelname.RSL file exists in the current working directory. The View Residuals function creates a line plot of the residual history for the current simulation. The Residual Plotter appears in a separate window.
There are several ways to customize the Residual Plotter. When you click the right mouse button on the Residual Plotter, a menu appears with the following items:
• Modify Axes
• Update Frequency
• Hide All Lines
• Normalize Residuals
• Export to Text File Control Panel
Run-View Residuals-Modify Axes
The Modify Axes option lets you change the axes of the plots. To reset the original axes, click the restore button on the panel.
Control Panel
Run-View Residuals-Update Frequency
The Update Frequency option enables you to modify the frequency in which the residual plotter is updated. The default update frequency is set to 100 ms.
Control Panel
Run-View Residuals-Hide All Lines
The Hide All Lines option urns off all lines from being plotted.
Control Panel
Run-View Residuals-Normalize Residuals
Normalizes the residuals so that the maximum residual plotted is one and all others are scaled appropriately so that they show the magnitude drop from the maximum residual.
Control Panel
Run-View Residuals-Export to Text File
The Export To Text File option enables you export the residual file to a format that can be used by Excel. If, upon pressing View Residuals you get a message that says no residual file available or you get a blank Residual Plotter window, it may be that the solver has not yet written any information to the residual history file. Close the Residual Plotter and reopen it after the residual history file has been created.
Residual Plotter Window
The buttons in the upper left-hand corner activate or deactivate the plotting for that particular variable. The Color Palette buttons open the Color Dialog panel to enable you to change the line color of the residual plot for that particular selected variable.
The Minor Grid lines checkbox draw more grid lines for the y-axis (logscale) of the plot.
If the simulation is unsteady (transient) then there are residual histories for each time step in the residual file. You can cycle through the time steps by using the slider at the bottom of the residual plotter window.
Control Panel Run-View Output
Once the CFD-ACE-SOLVER job has been submitted and the solver starts to write the output file (modelname.out), the View Output function becomes active. The function will also be active if a modelname.out file exists in the current working directory. View Output creates a text viewer of the output for the current simulation. The Output Viewer will periodically update to show you the output file information in near real time.
If you press View Output and get a message that says no output file available or you get a blank Output Viewer window, it may be that the solver has not yet written any information to the output file. Close the Output Viewer and reopen it after the output file has been created.
Control Panel
Run-Plot Monitor Points
The Monitor Point plotter can be invoked if the simulation has started running and you have requested that monitor point data be written as output (see Graphical Output ). The behavior of the Monitor Point plotter is very similar to that of the residual plotter.
Control Panel Run-Save and Stop
The Save and Stop option sends a signal to the CFD-ACE-Solver to immediately save the simulation data (restart and graphical data) and terminate the solver job. This allows you to safely terminate a CFD-ACE-Solver run if you determine that you do not want to run any further iterations.
Control Panel Run-Stop
The Stop option terminates the CFD-ACE-Solver immediately and does not save any data. This function should be used carefully since it does not save the results of the simulation. The DTF file will contain the results as of the last restart save operation, determined by the Output settings. See Output Options.
