13.1. Command-Line Use

CFX-Solver Manager and CFX-Solver can be launched, and command line help can be displayed, from the command line as follows:

To start CFX-Solver Manager, the basic command is:
```
cfx5solve
```
The general form of the command is:
```
cfx5solve -interactive [-definition <file>] [-display <display>]
```
where [ ] denotes a discretionary option, | separates mutually exclusive options, and < > denotes that substitution of a suitable value is required. All other options are keywords, some of which have a short form.
To start the CFX-Solver using a CFX-Solver input file (here, represented by <file>), the basic command is:
```
cfx5solve -definition <file>
```
The general form of the command is:
```
cfx5solve -definition <file> [-initial <file>]
[-double | -single]
[-nosave|-save] [-name <name>] [-size <factor>]
[-solver <executable>] [-partition <number of partitions>]
[-parallel] [-parfile <file>] [-serial] [-verbose]
```
where [ ] denotes a discretionary option, | separates mutually exclusive options, and < > denotes that substitution of a suitable value is required. All other options are keywords, some of which have a short form.
To display command line help, which shows descriptions for the available command line options, the command is:
```
cfx5solve -help
```

How you invoke a command line depends on your operating system:

On Windows, you can start a CFX command line from the Ansys CFX Launcher: Tools > Command Line. Alternatively, you can run CFX-Solver Manager from a Command Prompt. For details, see Command Line in the CFX Reference Guide.
