The Frequency Domain, AWE Reduced-Order Model () node is not a study in itself; rather, it adds a number of nodes to the Model Builder tree to facilitate a reduced-order model (ROM) creation. These nodes are configured to set up a ROM to perform a frequency-domain sweep using the asymptotic wave evaluation (AWE) technique.

One study with a Model Reduction study step, in which the ROM is created. The Model Reduction study step contains a Frequency Domain subnode. The purpose of that subnode is to provide the model reduction with information about equation forms, participating physics interfaces, mesh selection, and so on.

Under Global Definitions, a Reduced-Order Modeling node is added. It contains a subnode, which is a Frequency Domain, AWE Reduced-Order Model node. This is a placeholder for the ROM to be created.
