  - Simulation Templates: HVAC Duct
    In Simcenter STAR-CCM+, simulation templates define a starting point for simulations with similar physics. A simulation template can include a variety of predefined objects, such as predefined simulation operations, mesh operations, tags, filters, and parameters. Using a simulation template helps to automate and speed up the simulation preparation process.

      In this part of the tutorial, you adjust the simulation template to work with a HVAC duct that has not been prepared as a water-tight geometry.
    - 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.
      - Parameterizing the Coordinates
        Simcenter STAR-CCM+ allows you to specfiy the coordinates of certain parts, such as closures and refinements, using parameters. When importing a new duct with a different geometry or orientation into the previous simulation templates, the inflow volume, test chamber, refinements, and closures may not enclose the duct inlets or outlets. To resolve this, define the location and orientation of the closures and refinements using parameters.
      - Importing the Parts and Assigning the Tags
        Once you have created the parameters you require, import the parts and observe how the HVAC duct aligns with the template parts.

Adjusting the Parameters

Adjust the parameters that define the inflow volume, the vent refinement, the test chamber, and the closures so that they align with the new duct geometry.

To define the location and orientation of the misaligned parts, set the parameters associated with the DuctCenter and VentCenter coordinates:

Expand the Automation > Parameters > CoordinateSystems node and set the Value property for each parameter as follows:


Parameter	Value
DuctCenterOrigin	[-0.21, 0, 0] m
DuctCenterXAxisInput	[0, 0, 1]
DuctCenterXYPlane	[0, 1, 0]
VentCenterOrigin	[0.042, 0, 0]
VentCenterXAxisInput	[1, 0, 0]
VentCenterXYPlane	[0, 1, 0]

The current radius of the inflow volume is too small to cover the entire duct inlet.

To increase the radius of the inflow volume, select the Parameters > GeometryPartParameters > InflowVolRadius node and set Value to 0.08 m.

The duct closure is also too small to close the duct inlet.

To increase the dimensions of the duct closure, expand the Parameters > ClosurePartParameters and set the Value property for the duct closure parameters as follows:


Parameter	Value
DuctClosureCorner1	[-0.05, -0.05, -0.005]
DuctClosureCorner2	[0.05, 0.05, 0.005]

By observing the 01_InputGeometry scene, you see the model of the inflow volume does not update automatically once the parameters have been updated.

To update the CAD model of the inflow volume, right-click the Geometry > Parts > Geometry > InflowVolumeCAD node and select Update.
Open the 01_InputGeometry, 02_Closures, and 03_VentRefinement scenes to check the closures, vent refinement volume, inflow volume, and test chamber align with the new parameter defintions.
01_InputGeometry:

02_Closures:

03_VentRefinement:

With the simulation parts aligned, the simulation is configured to work with the new duct geometry.

To execute the simulation operations, click (Play/Resume "Simulation Operations 1") in the solution toolbar.
