Re: [Opm] OPM Query - From a New User
Hi David, It looks like you are using the tuning parameters I put in Pull Request 2669 in opm-simulators. If you compile Flow from git and include that PR, those will be your new defaults. I am surprised if those values are good for the Volve case though. You can add the line: use-cpr=True to the file if you want to test with CPR too. Please note that CPR got a complete make over recently. Not sure it made it into the latest release, so you may need to use Flow compiled from source later. In any case, if you only want to test CPR from the command-line, just run: flow VOLVE_2020ZZ_OPM.DATA --use-cpr=1 (I missed the =1 part in my previous mail, sorry). Regarding the a find facility, there are multiple ways you can search for a keyword. The manual is a pdf, and each keyword has a page with its name in the title. Hence, if you search in the "Contents" you will effectively search the keywords. You will need a pdf-viewer with a seperate search field for the "Contents" such as Okular. Please also note that all keywords are in alphabetical order, and on any page with keyword documentation, you will find a clickable alphabet at the bottom of the page. The idea is that any keyword should only be two clicks away. You can of course also do a free text search within the document itself if you want to search for a topic. Does this answer your need?

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….

Re: [Opm] OPM Query - From a New User
Hi,
Thank you for your interest in OPM Flow. I am sorry that you got such a rough
initial experience.
The 'TableContainer' is Flow's internal representation of property tables
entered using "simple" data keywords such as SWOF, PVDO, RSVD, and others.
This facility handles region support (e.g., partitioning a model according to
SATNUM or PVTNUM) as well as the case of the table data in certain regions
being defaulted (fallback to using tables from regions with lower numerical IDs
if available).
The exception message (no table in range 0..0) suggests that Flow, for whatever
reason, was not able to identify the table data for one or more of the tables
entered in one (or more) of the keywords. The segmentation fault *typically*
results from indexing out-of-bounds in an array. That's always a programming
error (failure to properly check the bounds of the array). As for the
Cartesian geometry, that's hard to explain. I would have to know a little bit
more about your case.
Since you refer to "segmentation faults" I'll assume that you're on a Linux
system. In that case, would you mind running the command
sed -n 's/\(^.*[0-9]\{1,\} *Reading [A-Z][A-Z0-9_]\{1,7\}\) *in
file.*$/\1/p' ./CASE.PRT
with "CASE.PRT" being the .PRT-file generated by Flow when running your
simulation case? The output of the above command is a list of the keywords
that Flow recognized in the input file, but without any identifying markers
(e.g., filenames, well names or line information). If you're not able to share
the model, that list might still help us narrow down a few possibilities and
make suggestions for things to try next. If you *are* able (and willing) to
share the model, then by all means feel free to send it to me by e-mail.
By the way, are you running a release version of Flow (e.g., 2020.04) or did
you compile the master sources from GitHub yourself?

Dear Member,
I am just starting to learn the ropes with OPM and have tried out some datasets
which run fine on Eclipse.
I have had various rather vague messages upon failure of the models to run:
* Program threw an exception: could not initialise the problem:
TableContainer does not have any table in the range 0...0
* Segmentation fault problem
* Convergence problems
* OPM does not seem recognise that a Cartesian grid had been specified
(specification was adequate for Eclipse).
I checked the manual (OPM_Flow_Documentation_2020-04_Rev-0), but could find no
reference to TableContainer or Segmentation fault I should be very grateful if
you could point me in the best direction to be able to overcome these type of
issues.
Kind regards,
