## 2.2. The Define Run Dialog Box

You access the Define Run dialog box from CFX-Solver Manager by clicking File > Define Run.

Under Solver Input File, ensure that the name of a CFX-Solver input file (with extension `.def` or `.mdef`) is specified.

The name will be set automatically if:

- You have started CFX-Solver Manager using the Define Run action in CFX-Pre.

- You have started CFX-Solver Manager from the command line using the `-interactive` and `-def` or `-mdef` options. For details, see Starting the CFX-Solver from the Command Line in the CFX-Solver Manager User's Guide.

  CFX-Solver input filenames must not contain spaces when run with an associated ANSYS input file (.inp). Note that in CFX-Solver Manager, when specifying or editing the Solver Input File by typing from the keyboard, you must click Reload run settings from file to have the changes take effect.

In CFX-Solver Manager, if a multi-configuration definition or results file (*.mdef or *.mres, respectively) is selected as the CFX-Solver Input file, then the settings on the tabs described below can be made on a simulation-wide or per-configuration basis. This is done by choosing either `Global Settings` or a specific configuration name for the Edit Configuration option. Note that when global settings are made, they are inherited by all configurations. You can then override any setting for a specific configuration, but it is important to note that in this situation the remainder of the settings for the configuration will not be inherited from the global settings.

The tabs of the Define Run dialog box that can be configured are described in the following sections:

- Run Definition Tab
- Initial Values Tab
- MultiField Tab
- Partitioner Tab
- Solver Tab
- Interpolator Tab
- Configuring Memory for the CFX-Solver
