I had some issues with the saturation properties which I’ve capped using OPERATE and that appears to be helping. I can let that play out and get back to you. Can I attach files to mailing list or what way to you all prefer to share things?

If not then if you send me the *.PRT, *.LOG and *.DBG files I'll have a quick look to see if there is anything obvious from these files. Also are you getting? |Time step 2, stepsize -nan days, at day 0.04/31, date = 01-Jan-2021 Error: [/build/opm-simulators-4CUPDM/opm-simulators-2019.10-rfinal/opm/simulators/flow/BlackoilModelEbos.hpp:268] NaN residual found!�[0m Problem: Solver convergence failure - Numerical problem encountered Timestep chopped to -nan days| || Nobody responded to my GitHub issue question "How Many Hours in a -nan Day? #2503 " - perhaps it was something of a "black-hole" to investigate :-). I don't' have a general solution to this, but I have resolve a few cases of the above due to data inconsistencies. Release 2020-04 is out, so perhaps you can try your model with the new release. || OPM User opmus...@gmail.com _______________________________________________ Opm mailing list Opm@opm-project.org https://opm-project.org/cgi-bin/mailman/listinfo/opm ________________________________ Founded in 1821, Heriot-Watt is a leader in ideas and solutions.
