Writing the Geometry and Problem Files and Saving the Model
Finally, write the STAR geometry and problem files and save the pro-STAR model file (see Figure 23-53).
•From the main pro-STAR menu bar, select File > Save Geometry to open the
Save Geometry File panel
•Set the Geometry Scale Factor to 0.001 and click Apply followed by Close
•Select File > Save Problem and click Save
•Select File > Quit and click Save & Quit
