A running TRACE computation can be controlled by creating a file in the working directory, e.g. using the touch command. After the command is executed by TRACE, the file is removed from the working directory.

The following commands are available:

Command	Description
`terminateTRACE`	Terminates the TRACE simulation after writing all specified output data.
`writeSolution`	Writes out 3D flow field data to the specified output file.
`writeSurfaceData`	Writes out 2D data on the surfaces of the computational domain to the specified 2D output file.
