On Workbench's Project Schematic, verify the state of each Setup cell, as follows:
The Setup cell for both the Transient Structural and the Fluid-Flow (CFX) systems should be in an Up-to-Date ( ) state.
The Setup cell for the System Coupling system should be in an Attention Required ( ) state. (If it is in a Refresh Required state, right-click the cell and select Refresh.)
Note: This tutorial focuses on exporting a partial setup. To export a full setup, you would finish the co-simulation setup in Workbench, not performing the export until the System Coupling system is also in an Up-to-Date ( ) state.
