[[Image:fdtd_lec1_21_datamanagerpng|right]] EM.Cube’s computational modules usually generate two types of data: 2D and 3D. Examples of 2D data are probe fields, S/Z/Y parameters and polar radiation patterns. 2D data are graphed in <b>EM.Grid</b>. Examples of 3D data are near field distributions and 3D radiation patterns. 3D data are visualized in EM.Cube’s project workspace and the plots are usually overlaid on the physical structure.
A list of all the 2D output data files generated at the end of a simulation can be viewed in EM.Cube’s Data Manager. To open this dialog, click the <b>Data Manager</b> [[Image:fdtd_datamanagerb.png]] button of Simulate Toolbar, or use the keyboard shortcut <b>Ctrl+D</b>, or access the menu <b>Simulate → Data Manager</b>, or right click on the Data Manager item in the “Observables” section of the Navigation Tree and select <b>Open Data Manager…</b>
Select the two data files “Probe_1_E_Time” and “Probe_1_H_Time” and click the Plot button of Data Manager to open <b>EM.Grid</b>. For multiple file selection, use the keyboard’s <b>Ctrl Key</b>, or use the <b>Shift Key </b> to select a range of rows in the list. The Ex and Hx field components are plotted as functions of time on two Cartesian graphs in EM.Grid.
