WELTRAJ and COMPTRAJ stopped working

[HvOeveren]

For release 2025.10 it worked fine to use the WELTRAJ and COMPTRAJ approach for wells.
For release 2026.04 the same decks have stopped working, and I have to use COMPDAT again.

I am using OPM flow for geothermal, WATER, THERMAL.
I describe wells with multiple perforation intervals over multiple reservoirs.
Cross is flow enabled. Tracers are enabled.
Deck runs well using COMPDAT.

I would prefer to use WELTRAJ to change out the grid for other realisations.

Happy to help further with this issue.

Thanks a lot for the report. We would probably need to understand what "stopped working" means more precisely.

Does the simulator abort? Then it would be good to some of the output (PRT or output in the terminal) before that.

Ideally you would provide a small test case demonstrating the problem.

Thank you Markus, I will prepare an example deck showing the issue.
Because I'm a bit tied up, I will try to upload this in 3 weeks.
