The used surrogate model is the combination of the 1D Python solvers TubeFlow and TubeStructure.
This is reflected in a different coupled solver and corresponding models, and the type of predictor. This example is identical to the example Fluent2D and Abaqus2D, except for the use of a surrogate model.
