Once all of the data have been entered, and a Plan has been defined, the unsteady flow computations can be performed by pressing the Compute button at the bottom of the Unsteady Flow Simulation window. When the compute button is pressed, a separate window will appear showing you the progress of the computations (Figure 7-28). The information that appears in the window is an indicator of the programs progress during the computations, and a list of any computational messages that come up during the run. When the computations have been completed, the user can close the computations window by clicking the upper right corner of the window, or the close button at the bottom. If the computations ended normally (i.e. all of the processes ran with no error messages), then the user can begin to look at the output. If the program does not finish normally, then the user should turn view the computational messages to see what problems may have occurred, then begin debugging the problem.
