### 20.1.2. Basic Settings for Steady-State Simulations

#### 20.1.2.1. Convergence Control: Min. Iterations

The minimum number of iterations the CFX-Solver will run.

#### 20.1.2.2. Convergence Control: Max. Iterations

The maximum number of iterations the CFX-Solver will run.

For details, see Max. Iterations in the CFX-Solver Modeling Guide.

#### 20.1.2.3. Convergence Control: Fluid Timescale Control

Sets the method of time scale control for a simulation. For details, see Time Scale Control in the CFX-Solver Modeling Guide.

Three options are available for steady-state simulations:

- `Auto Timescale`: For details, see Auto Timescale in the CFX-Solver Modeling Guide and Automatic Time Scale Calculation in the CFX-Solver Theory Guide.

  - Length Scale Option

    Three options are available: `Conservative`, `Aggressive` or `Specified Length Scale`.

- `Local Timescale Factor`: For details, see Local Time Scale Factor in the CFX-Solver Modeling Guide.

- `Physical Timescale`: For details, see Physical Time Scale in the CFX-Solver Modeling Guide.

#### 20.1.2.4. Convergence Control: Solid Timescale Control

This option is available in a steady-state simulation when a solid domain, or a solid within a porous domain, is used. Two choices are available: `Auto Timescale` and `Physical Timescale`.

- Solid Timescale Factor: This option is available when `Auto Timescale` is used as the Solid Timescale. For details, see Solid Time Scale Control in the CFX-Solver Modeling Guide.
