Changes
In this tutorial you will learn how to build and analyze wire structures. You will use a new type of source called gap source.
==Getting Started==
Open the [[EM.Cube]] application. Click <b>Start</b>, select <b>All Programs</b>, and then the <b>EMAG</b> program group. Select <b>[[EM.Cube|EM.CUBE]]</b> switch to start the program. By default, [[EM.CubeLibera]] opens up a blank project with the name “UntitledProj1” in its [[CubeCAD]] Module. You can start drawing objects and build up your physical structure right away. Or you can initiate Start 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 “[[WMOMLesson1]]”. 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. {{isoimg|fdtd_lec1_1_module.png|[[EM.Cube]]'s project workspace.}}{{isoimg|fig-WMOMLesson1new.png|The New Project Dialog.}} [[EM.Cube]]’s [[CubeCAD]] Module lets you construct 3D geometries, or import them via external model files such as *.stp, *igs, or *.stl. Once these geometries have been modified or completed, they can be moved to other modules within [[EM.Cube]] for further simulation. On the other hand, all modules of [[EM.Cube]] offer full CAD operations by themselves. Therefore, you can build a new project from the ground up in any of [[EM.Cube]]’s computational modules. ==MoM3D Module Navigation== [[Image:modules.png|thumb|540px|right|EM.Cube's Module Toolbar.]] To navigate to [[MoM3D Module|MoM3D Module]], simply select its icon from the Module Toolbar on the left side of the screen. Any module may be selected this way. Selecting the module icon changes the Navigation Tree to represent the types of objects supported by the current module. The Navigation Tree of all computational modules features the following nodesparameters: Physical Structure, Computational Domain, Discretization, Sources, and Observables.
