[[EM.Cube]] brings together several computational modules that can be used to solve a large variety of electromagnetic modeling and RF design problems. Each module revolves around a specific numerical method that is optimized for a certain class of problems or applications. [[EM.Cube]]'s framework is based on total separation of the visual software interface and simulation engines. The numerical solvers communicate with the [[EM.Cube]] application solely through ASCII input and output files. This creates the opportunity to utilize the same user interface effectively to drive different simulation engines.
At the heart of [[EM.Cube]] is [[Building_Geometrical_Constructions_in_CubeCAD | CubeCAD]], a general-purpose parametric CAD modeling environment. [[EM.Cube]]'s computational modules are all customized variations of [[Building_Geometrical_Constructions_in_CubeCAD | CubeCAD ]] equipped with a particular simulation engine. Therefore, they all share the same input utilities (geometry definition and mesh generation) and same output utilities (data visualization and processing). [[Building_Geometrical_Constructions_in_CubeCAD | CubeCAD ]] features a powerful 3D CAD modeler with a large selection of native objects (solids, surfaces, curves) and a wide range of object creation, editing and transformation tools. You can import external CAD files with different popular standard formats. [[Building_Geometrical_Constructions_in_CubeCAD | CubeCAD]]'s intuitive, mouse-driven tools let you quickly build very sophisticated structures either from the ground up or by combining native objects with imported external structures. You can also export your projects to a number of popular CAD formats. [[Building_Geometrical_Constructions_in_CubeCAD | CubeCAD]]'s Data Manager is a versatile utility for processing and plotting your simulation data either as 3D visualizations or in a variety of graph types.
Besides sharing a common CAD modeler and common data visualization tools, all computational modules also feature a hierarchy of common elements:
* '''System Toolbar''': This toolbar is used for general project operations as well as general edit functions.
* '''View Toolbar''': This toolbar provides buttons for most widely used view operation such as zooming and work planes.
* '''Object Toolbar''': This toolbar contains all the tools for drawing [[Building_Geometrical_Constructions_in_CubeCAD | CubeCAD]]'s native geoemtric object types.
* '''Tools Toolbar''': This toolbar provides a large number of geometric object editing and transformation tools.
* '''Wizard Toolbar''': This toolbar provides access to all of [[EM.Cube]]'s preloaded wizards.
=== Module Bar ===
When you start the [[EM.Cube]] application, it lands you first in [[Building_Geometrical_Constructions_in_CubeCAD | CubeCAD ]] by default. The Module Bar located on the left edge of the screen is used to switch among [[Building_Geometrical_Constructions_in_CubeCAD | CubeCAD ]] and [[EM.Cube]]'s various computational modules. It consists of eight buttons:
*'''[[Building_Geometrical_Constructions_in_CubeCAD | CubeCAD]]''': [[EM.Cube]]'s 3D CAD modeling environment
The Navigation Tree provides all the details of an entire [[EM.Cube]] project. These include the CAD objects and geometric models, material assignments, computational domain and boundary conditions, mesh structure, source information, observable definitions, etc. Besides the menu bar and toolbars, the navigation tree serves as another place from which you can modify most items in your project. Similar to the toolbars, you can undock, move around or hide the module bar and navigation tree.
The contents of the navigation tree vary depending on the selected module. In [[Building_Geometrical_Constructions_in_CubeCAD | CubeCAD]], the navigation tree features two main sections: Geometrical Construction and Data Visualization. The "Geometrical Construction" section holds your geometric objects, while the "Data Visualization" section is used for generation of 3D data visualizations to be displayed in the project workspace. In other modules, the navigation tree typically features five distinct sections:
