   The Expert Parameters details view appears.

2. Make changes to the appropriate sections on any of the following tabs: Discretization, Linear Solver, I/O Control, Convergence Control, Physical Models, Particle Tracking, or Model Overrides.

   Making changes requires selecting options and setting specific values. For parameters with a small number of choices (such as logical parameters), select an option from the drop-down list. Other parameters require data entry (such as real numbers).
