=== set comfile ===

 '''set comfile''' ''INFILE'' ''OUTFILE''
Defines the communication files used in the file-based coupled calculation communications. Input values:

{|
| <tt>''INFILE''</tt>
| : Path to inwards communication file (signals to Serpent).
|-
| <tt>''OUTFILE''</tt>
| : Path to outwards communication file (signals from Serpent).
|}

<u>Notes:</u>

*Setting up a communication mode will enable the coupled calculation mode.
*The communication options [[#set comfile|set comfile]], [[#set ppid|set ppid]] and [[#set pport|set pport]] are mutually exclusive, aka, multiple signalling modes are not allowed.
*For more information, see the detailed description on [[Coupled_multi-physics_calculations#External_coupling|external coupling]]
