Fix thermal well perforation energy flux

[npillardou]

This PR tries to fix a thermal well issue at top perforations.

According to the image below, for a single phase water injection, the temperature drops significantly lower than injection temperature (293.15K ) which is not logical for water injection case (left figure).

Hi Nicolas

Could you upload the associated model. There is a restriction, probably not documented, where the top segment cannot contain a perforation.
Thanks

Could you move/change the perf/seg definition so that the top seg doesn't have a perf and then make the comparison. Currently it looks like the top seg has 2 perforations...

Hello Thomas,
I updated the xml file with perforation like you suggested. However, the same issue appear in the top layers.

I also noticed a MGR issue when the injection starts from 0, I don't know if it is also your case :

    <TableFunction
      name="injectorTotalRateTable"
      inputVarNames="{ time }"
      coordinates="{  0, 100.0e6 }"
      values="{ 1e-2, 1e-2 }" 
      interpolation="lower"/>
