T2 = GRP2GRP

N1 = GRP2GRP (or 81) prints heat flows to the report log file between groups N1 and T1, both of which must be group names. This option is similar to the HFGROUP option, and is useful for model debugging.

T1 may be the symbol *, in which case the heat flows from the group N1 to all the elements in the model will be printed.

T1 may be the keyword _SINKS, in which case the heat flows from the group N1 to all the sink elements or groups are calculated.

Heat flows through the different modes of heat transfer are calculated as follows:

Conductive heat flows are calculated only between groups that have direct conductive heat paths between each other, i.e. they share common edges or surfaces.
Convective heat flows are calculated by summing the heat flows through the non-radiative thermal couplings between the two groups.
Radiative heat flows are calculated by summing the heat flows through the radiative thermal couplings, plus the direct radiative couplings calculated by Gebhardt’s Method.
If Oppenheim’s Method was used to calculate radiative heat transfer, a two-step method is used to calculate the heat flows. In step 1, all non-Oppenheim elements are set to be sinks of temperature of zero, except for the N1 elements, which are set to their proper temperatures. The temperatures of all Oppenheim elements are then computed with the CG solver, and QN1T1, the heat flow from N1 to T1, is calculated. In step 2, all non-Oppenheim element temperatures are set to zero except for the temperatures of the group T1, and QT1N1, the heat flow from T1 to N1, is calculated. The net radiative heat flow between the two groups is QN1T1 – QT1N1.

Average temperatures of the groups are calculated by simple averaging.

The equivalent radiative, convective, or conductive conductances are calculated by dividing the appropriate heat flow between the groups by the difference in their average temperatures. In cases where large temperature gradients exist within a given group, this may yield counterintuitive results.

The functionality is identical to the CALL GRP2GRP option in the card 10 user-written subroutine.

T2 = IRRADIFL

N1 = IRRADIFL (or 129) prints elemental irradiance heat flux to the CAE results file.

The net radiative heat flux leaving a surface is equal to the difference between the radiosity and the irradiance:

The radiosity of a surface Qout is the outgoing radiative heat flux that consists of the emitted and reflected flux from that surface.

The irradiance of a surface Qin is the incident radiative heat flux from all other surfaces.

ε is the surface emissivity,
σ is the Stefan-Boltzmann constant,
