**External CFD Coupling for Compressible Volumes**
Input for coupling between PRIMAR-4 Compressible Volumes and an external code can be changed during a restart. However, it is up to the user to ensure that the models in force at the end of one simulation and the beginning of the subsequent simulation are consistent. This restart capability is primarily intended to allow a stand-alone, steady-state transient to converge efficiently prior to restarting the simulation with a more computationally intensive CFD model. In this scenario, the input below would not be present in the stand-alone model, but would be present in the restart input.

| > 0, Use scaled-time coupling.
When scaled-time coupling is used, long null transients in |SAS| will be projected to the external CFD models as shorter transients to help minimize CFD overhead during the null transient. Specifically,
the CFD time steps will be smaller than or equal to the null transient time steps in |SAS| according to the relation
.. math:: \Delta t_{\mathrm{\text{CFD}}} = \frac{\Delta t_{\mathrm{\text{SAS}}}}{\mathrm{\text{NULLCFD}}}
.. sasinp:: ICFDDBG
:location: 1412
Debug flag for CV to CFD coupling.
The complete history of data transferred from |SAS| to an external CFD model is always saved to a separate file. This flag adds additional debugging information to the normal output file.

* - Variable

- Description
* - NBINOT
- 891
- The number of IBINOT entries for the binary output file. If NBINOT=0, no PRIMAR4.dat output will be generated.
* - IBINST
- 892
- Output every IBINST PRIMAR time steps, default=1
* - IBINOT(K),

- 893-972
- Identification of binary output.
IBINOT is a 6-digit code where
- The first 2 digits give IBNTYP, the type of variable (or data item)
- The last 4 digits give the subscript INUM for the element, segment, temperature group, etc.
There is a special case where INUM>5000, in which case INUM-5000 is the starting value for a range of subscripts and the next INUM is the last value in that range.
*Examples*:
240006:
- IBNTYP=24, INUM=6. Print the liquid temperature of CV\ :sub:`6`.
10015:
- IBNTYP=1, INUM=15: Print the liquid segment flow of S\ :sub:`15`
245001 08:
- First IBNTYP=24, INUM=5001
- Second IBNTYP is blank, INUM=8
- Print the liquid temperature of a range of compressible volumes from CV\ :sub:`1` to CV\ :sub:`8`.
The notation for the subscripts in :numref:`table-A2.2-2` is as follows:
- ISGL = liquid segment
- ISGG = gas segment
- IELL = liquid element
- ICH = channel
- ICV = compressible volume
- IDHX = air dump heat exchanger
- INOD = node
- ITGP = temperature group
- IPMP = pump
- K, J = context specific
- L = 1 for inlet, 2 for outlet
