As previously discussed, a simulation requires that the user define a set of objects, simulation region, sources and monitors. As a complete setup may contain a large number of objects, the object tree was designed to allow for organization and easy selection. All simulation objects are within the group, model, which represents the current simulation. Within 'model', objects are listed as they are inserted by the user. Press F2 or double-click to change the name.
To move the objects up and down the tree as well as into groups, we use the orange arrows at the top of the window. The up and down arrows shift the objects relative to each other, while the left and right arrows move them out of and into groups. To add groups, we use the button called groups in the main toolbar. Structure groups can only contain structures and likewise, analysis groups can only contain monitors. See the online user guide section for more information and examples about Structure groups. The third group, "Containers" act like folders and can hold any type of object. In the image above, the 'Sources/Monitors' container group has both individual sources and monitors as well as an analysis group.
Note that there are buttons with green crosses at the top of the objects tree. These buttons can be used to hide or display certain types of objects. When objects are selected, they are highlighted blue in the objects tree and the vertices are marked with red squares in the view ports. Objects can always be selected by left-clicking on their name in the object tree or edited by right-clicking. Using the tree is the preferred method of selection especially in complicated simulation setups with many overlapping elements. In the image above, the power monitor, above, is selected.
Enable/Disable Simulation Object
User can enable/disable simulation objects by right-clicking on each and selecting "Enable/Disable". Disabled simulation objects will remain in the object tree (and can be re-enabled), they will have no effect on the simulation.
Note: Disabling objects does not reduce the file size
In some situation, the file size can be large due to the amount of data the project file carries, eg, doping profile. Disabling the import doping object does not reduce the file size. One way to reduce the file size is to remove the import doping object from the objects tree. This can help in situation where a small size file is required, such as making an email attachment.
