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 Simulation 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 Simulation CFD.
• In the Design Study Manager select the Design you wish to update (usually the newly added clone).
• In Autodesk Simulation CFD, confirm that no settings are lost and run the analysis.

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