Or you can initiate a new project by selecting the <b>New</b> [[Image:fdtd_newb.png]] button of the System Toolbar (or using the keyboard shortcut <b>Ctrl+N</b>, or via the menu <b>File → New Project…</b>). This opens up the New Project Dialog, where you can enter a title for your new project and set its path. You can use the Windows Explorer to go to the desired folder where you want to place your new project folder. For this project, use the title “FDTDLesson1”. From the same dialog, you can also set the project’s Length Units, Frequency Units, Center Frequency and Bandwidth. For this tutorial lesson, set the length and frequency units of the project to <b>Millimeters</b> and <b>Gigahertz</b>, respectively, and set both the center frequency and bandwidth to 1GHz. Then, click the <b>Create</b> button of the dialog to accept the settings. A new project folder with your given name is immediately created at your specified path.
