Step 7: Changing the Geometry in ANSYS DesignModeler

Now that you have two separate, but equivalent, ANSYS FLUENT-based fluid flow systems to work from, you can make changes to the second system without impacting the original system. In this step, you will make a slight alteration to the elbow geometry in ANSYS DesignModeler by changing the diameter of the smaller inlet.

1.   Open ANSYS DesignModeler.

Double-click the Geometry cell of the new-elbow system (cell B2) to display the geometry in ANSYS DesignModeler.

2.   Change the diameter of the small inlet ( velocity-inlet-small).

(a)   Select Sketch3, under Extrude1 to open the Details View of the small inlet extrusion.

(b)   In the Details View, under Dimensions:1, change the R1 (radius) value from 0.5 in to 0.75 in.

(c)   Click the Generate button to generate the geometry with your new values.

3.   Close ANSYS DesignModeler.

4.   View the files generated by ANSYS Workbench.

Note the addition of the geometry, mesh, and ANSYS FLUENT settings files now associated with new duplicated system.
