Settings in Ansys Forte are specified in Editor panels, which are accessed according to the selected item in the Workflow tree. Each panel presents a group of related settings or options. The Editor panels allow you to specify parameter values describing the physical system and operating conditions, and to select appropriate model options. Availability of panels may depend on selections made in the Workflow tree. For example, if the Spray Model option is turned ON (checkmarked) in the Workflow tree, the Spray Model node becomes expandable and the Spray Model Editor panel itself displays several spray-injection model options.
