Question: How do I use save files to restart an AERMOD run that was interrupted?

Answer: Load your model into BEEST and go to the Control Options form. Click the "CO Files" tab. Click the File button next to the "INITFILE option" file entry textbox. Browse to the location of your save file and select its name. Next, click the File button next to the save file name and select a different name for the save file. This is necessary to avoid having the original save file overwritten when AERMOD starts running. Finally, click the "Run AERMOD" button and run the model again.
