Using Parameterized Coordinate Systems

As is common within industry, you may be required to test multiple geometries for a similar application so you can compare the designs.

In the third part of this tutorial, you define the coordinate systems associated with the duct and vent parts using parameters. The vent refinement, closures, and inflow volume location and orientation are dependent on the duct and vent coordinate systems; parameterizing the coordinate systems allows you to quickly configure these parts for a different HVAC duct geometry.
In part three of this tutorial, the HVAC duct geometry differs in angle, length, shape, and cross-section to the previous geometry:
