Chapter 21: Cloning Designs and Scenarios

Previous: Exercise 14 | Next: Exercise 15

The greatest savings in time and money are rarely realized by running a single analysis. The true benefits of Upfront CFD come from running multiple analyses to compare different designs and different operating conditions. Autodesk® CFD enables you to do this quickly and easily be leveraging your first analysis and allowing you to make copies – called “clones” – that are easily updated.

Remember that an analysis has at least one Design, or unique geometry, associated with it. Each Design has at least one Scenario – set of operating conditions, materials, etc. – associated with it. You can clone either of these to leverage the work you have already accomplished.

Cloning a scenario…

Clone a scenario to study the effects of changing analysis settings or parameters on the same geometry configuration. Some examples of settings include the following:

• Materials
• Boundary Conditions
• Mesh Settings
• Environment settings

To clone a scenario:

1. Right click on a scenario in the Design Study Bar
2. Select clone, and assign a name.

Modify the settings as needed, and run the analysis.

Cloning a design…

Clone a design to study the effects of different geometry configurations:

To clone a design:

• Right click on the design name in the Design Study bar, and select Clone. Assign a name.
• Return to the CAD system and modify the design.
• Launch into Autodesk® CFD.
• In the Design Study Manager select the Design you wish to update (usually the newly added clone).
• In Autodesk® CFD, confirm that no settings are lost and run the analysis.

After solving all analyses, compare them to each other in the Decision Center.
