Feedback Iterator
Background Information
Prior to the introduction of the Feedback Iterator, Ansys Workbench supported a two-way loose-coupling protocol with Ansys Electromagnetics products.
- System Coupling uses the word “coupling” to mean low-level solver coupling. Existing Ansys Electromagnetics coupling is “loose” when compared to System Coupling and is limited to file transfers at the end of a complete solve in a stand-alone system/product. No communication occurs during a solve.
- The coupling is two-way:
The one-way portion (Upstream source component to Downstream target component) is handled via existing Workbench data/transfer connection mechanism.
The round trip is handled by a separate protocol agreed upon by the participating systems when the downstream system exports a set of file to a location specified by the upstream system (via its one way transfer). This exported data is then incorporated by the upstream system in its next update.
If the user chooses to run the next coupled solve iteration, the user invokes the Enable Update command as shown below and then updates all systems involved. These steps (Enable Update, Update Project) are continued as long as needed.
The Feedback Iterator system automates this process as detailed in the following related topics:
