Step 6: Duplicating the ANSYS FLUENT-Based Fluid Flow Analysis System

At this point, you have a completely defined fluid flow system that is comprised of a geometry, a computational mesh, a CFD setup and solution, and corresponding results. In order to study the effects upon the flow field that may occur if you were to alter the geometry, another fluid flow analysis is required. One approach would be to use the current system and change the geometry, however you would overwrite the data from your previous simulation. A more suitable and effective approach would be to create a copy, or duplicate, of the current system, and then make the appropriate changes to the duplicate system.

In this step, you will create a duplicate of the original ANSYS FLUENT-based fluid flow system.

1.   In the Project Schematic, right-click the title cell of the Fluid Flow (FLUENT) system and select Duplicate from the context menu.

Figure 1.29: The Original Fluid Flow System and Its Duplicate

   Notice that in the duplicated system, the state of the Solution cell indicates that the cell requires an update while the state of the Results cell indicates that the cell requires attention. This is because when a system is duplicated, the case and data files are not copied to the new system, therefore, the new system does not yet have solution data associated with it.

2.   Rename the duplicated system to new-elbow.

3.   Save the elbow-workbench project in ANSYS Workbench.
