Modules Panel
The Modules panel allows users to activate and enable the optional add-on modules.
Activating a module checks out a license seat for the module.
Enabling a module turns on all functionality for the module. By default activating a module will also automatically enable the module for use. Disabling a module keeps the license seat checked out but the module calculations are not applied to the model. Disabling a module may be desired for various reasons, as is discussed further for each module below.
Note: A module specific license is required to activate the GSC, XTS, or ANS add-on modules.

GSC (Goal Seek & Control)
Activate the Goal Seek & Control module by checking the box next to Activate GSC. Once activated, enable it by selecting Use or disable it by selecting Ignore. When the GSC module is activated, the Goal Seek and Control Group appears in the Analysis Setup window. The Goal Seek and Control group has three items: Variables, Goals, and Numerical Controls.
The GSC module can be enabled before or after a model is built. Pre-existing models built with the base AFT Arrow application can have the GSC module activated.
Setting the GSC module to Ignore causes the GSC module to function like the base AFT Arrow application. One difference is that users are still able to enter goal seeking data with this data retained in the model. If the model is opened in the base AFT Arrow application, this data will be lost. Table 1 relates the differences between using AFT Arrow without the GSC module activated, using it with the GSC module activated but disabled (Ignore mode), and using it with the GSC module activated and enabled.
The GSC module can also be toggled between Use and Ignore from the Analysis menu in the Goal Seek & Control option as shown in Figure 2. Use this feature to quickly toggle the GSC module between Use and Ignore without opening the Modules panel in Analysis Setup.

XTS (Extended Time Simulation)
Activate the Extended Time Simulation module by checking the box next to Activate XTS. Once activated, enable it by selecting Transient or disable it by selecting Steady Only. When the XTS module is activated, the Transient Control group appears in the Analysis Setup. The Transient Control group has one item: Simulation Duration.
Activating the XTS module can be done before or after a model is built. If activated after, then additional input will be required for transient junctions. Pre-existing models built with the base AFT Arrow application can have the XTS module activated.
Transient modeling can be turned off at any time by selecting Steady Only. The Steady Only mode causes the XTS module to function like standard steady-state AFT Arrow. One difference is that users can still enter transient data and this data is retained in the model. If the model is opened in standard AFT Arrow, this data will be lost. Additionally, the Transient Control group and Simulation Duration panel are still accessible. Table 4 relates the differences between not using XTS and using it in Steady Only mode.
The XTS module can be toggled between Steady Only and Transient from the Analysis menu in the Time Simulation option as shown in Figure 4. Use this feature to quickly toggle the XTS module between Steady Only and Transient without opening the Modules panel in Analysis Setup.

| XTS Disabled | XTS Enabled | ||
| Transient Control Group in Analysis Setup | Not Visible | Visible | Visible |

ANS (Automated Network Sizing)
Activate the Automated Network Sizing module by checking the box next to Activate ANS. Once activated, enable it by selecting Network or disable it by selecting Not Used. When the ANS module is activated, the Automatic Sizing group appears in the Analysis Setup. The Automatic Sizing group has one item: Sizing Summary. Additionally, the Sizing Window becomes available when ANS is activated.
Activating the ANS module can be done before or after a model is built. If activated after, then additional sizing data will be required to run the model. Pre-existing models built with the base AFT Arrow application can have the ANS module activated.
ANS can be disabled at any time by selecting Not Used from the same menu. The Not Used mode causes the ANS module to function like the base AFT Arrow application. However, all ANS data and settings in the model will still be retained. If the model is opened in the base AFT Arrow application, this data will be lost. The purpose of Not Used mode is that it allows ANS to be quickly turned off and on without having to change data in the Sizing Objective.
The ANS module can be toggled between Network and Not Used from the Analysis menu in the Automated Sizing option as shown in Figure 5. Use this feature to quickly toggle the ANS module between Network and Not Used without opening the Modules panel in Analysis Setup.
