      Sometimes it is desirable to calculate a minimal number of iterations before ANSYS Fluent starts checking the convergence. Reasons can be slow convergence behavior of certain quantities (i.e. temperature for CHT cases (conjugate heat transfer)) or transient simulations with different convergence behavior at certain stages of the progress. Fluent doesn’t provide a direct control to specify a minimal number of iterations but you can use different approaches to get a similar behavior. See the attached document for a detailed description
