Hi Alf, Thank you for your email. My simulation is run using the following command: flow --parameter-file=VOLVE_2020ZZ_OPM.PARAM where VOLVE_2020ZZ_OPM.PARAM is as per the attached file. Would your command "$ flow DECK.DATA --use-cpr" (modified as required) be put in the .PARAM file? Similar question regarding "$ flow -h"? Regarding your "See all parameters with....", a "find" facility (when searching for keywords etc.) does not seem to be available for the OPM manual (link below). This makes getting best value from this large manual extremely difficult! Am I missing something here and is there a solution? Grateful for advice on any of the above. Thanks for the tip regarding MINPV.... Kind regards, Dave

CPR keyword is ignored because the implementation in Flow is immature. Use it like this: $ flow DECK.DATA --use-cpr You can also force usage of TUNING with command line parameter. See all parameters with: $ flow -h Flow supports MINPV and PINCH, which is the commonly used in Eclipse.

I have a few issues to try to overcome: >From the OPM Manual >https://opm-project.org/wp-content/uploads/2020/08/OPM_Flow_Documentation_2020-04_Rev-1.pdf TUNING keyword (page 1479) "TUNING defines the parameters used for controlling the commercial simulator's numerical convergence parameters for the global grid. The keyword is mostly ignored by OPM Flow; however, the simulator can be instructed to read the first record of the TUNING keyword if the appropriate command line parameter has been activated (see section 2.2 Running OPM Flow 2020-04 From The Command Line)." * I tried inserting TUNING into the SCHEDULE section of a dataset, it indeed had no effect. * I cannot find an "appropriate command line parameter" in Section 2.2 Running OPM Flow 2020-04 From The Command Line. Also a "find" facility (when searching for keywords etc.) does not seem to be available for the manual. I would like to get OPM to use CPR as the linear solver's pre-conditioner (Eclipse has a keyword CPR, which is apparently not supported by OPM). The necessary command is detailed as --use-cpr in the OPM manual (page 56). I'm not sure how to apply this. Grateful if anyone could advise. OPM does not seem to have a MINPORV option? Does anyone know if there is a workaround for this? I should be very grateful if you could point me in the best direction to be able to overcome any of the above issues.
