=== ifc (interface file)<span id="ifc"></span> ===

 '''ifc''' ''FILE'' [ [[#ifc_setinmat|'''setinmat''']] ''N<sub>MAT</sub>'' ''MAT<sub>1</sub>'' ''MAT<sub>2</sub>'' ... ''MAT<sub>N<sub>MAT</sub></sub>'' ]
          [ [[#ifc_setoutmat|'''setoutmat''']] ''N<sub>MAT</sub>'' ''MAT<sub>1</sub>'' ''MAT<sub>2</sub>'' ... ''MAT<sub>N<sub>MAT</sub></sub>'' ]

Links a [[Multi-physics interface|multi-physics interface]] file to be used with the current input. The first parameter:

{|
|<tt>''FILE''</tt>
|: path to the multi-physics interface file
|}

The remaining parameters are defined by separate key words followed by the input values, being optional.

<u>Notes:</u>
*See also [[Coupled multi-physics calculations]].


<u>Optional entries:</u>

Interface input materials  (<tt>'''setinmat'''</tt>): <span id="mix_setinmat"></span>

{|
| <tt>''N<sub>MAT</sub>''</tt>
| : number of input materials to link to the interface
|-
| <tt>''MAT<sub>n</sub>''</tt> 
| : name of the ''n''-th input material linked to the interface
|}

<u>Notes:</u>
*It adds the possibility to link multiple input materials to the same interface, i.e. the same interface gives temperatures and densities (density factors) for multiple materials.
*If multiple input materials are linked to the interface using the option, the densities in the interface file must be given as density factors, i.e. relative to the material card density (values between 0 and 1).
*If the interface is not updated, the entry is not eligible. 
*If the regular mesh-based interface is used and power is tallied in pin-type objects, the entry is not eligible.
*The option '''<tt>setinmat</tt>''' is referred as '''<tt>setmat</tt>''' up to version 2.1.31.


Interface output materials  (<tt>'''setoutmat'''</tt>): <span id="mix_setoutmat"></span>

{|
| <tt>''N<sub>MAT</sub>''</tt>
| : number of output materials to link to the interface
|-
| <tt>''MAT<sub>n</sub>''</tt> 
| : name of the ''n''-th output material linked to the interface
|}
