Skipping Adjoint Iterations in Ansys Fluent Gradient-Based Optimizer

How do you skip over the flow and adjoint iterations for the first design iteration when using the Ansys Fluent gradient-based optimizer?

If you have an existing solution from the flow or the adjoint calculation, you might want to skip over the initial calculations when starting the automated optimization process with the gradient-based optimizer for shape or turbulence model optimization.

In the optimizer, you can simply set the number of iterations to zero for both calculations. Then access the “Execute Commands…”, either from the “Gradient-Based Optimizer” window or from Design > Gradient-based > Calculate… > Calculation Activities > Execute Commands…

Add one or two new commands with the lines:
/adjoint/optimizer/settings/adjoint-iterations 20
/adjoint/optimizer/settings/flow-iterations 200

Adjust the numbers in these lines according to your calculation requirements. You must execute this repeatedly.
