[Opm] OPM Query - From a New User

[Alf Birger Rustad]

Hi David,

Thanks for sharing! Like Bård says, a segmentation fault is a bug, and ideally should be reported as such in a manner reproducible by developers.

Convergence problems are hard to assess without knowledge about the model at hand. Generally speaking they will probably occur more frequent with Flow than with Eclipse as the numerics have had less time to mature. We are working very hard to improve that situation though, and on the models we have access to, the results are typically very good.

On a general note, Flow is more strict than Eclipse, and will more often fail if there is an error in the input data. There is of course also many keyword usages that work in Eclipse, but not in Flow. The error messages need to improve further in these cases. We very much want to know what caused the failure in your case, e.g., by you opening an issue on https://github.com/OPM/opm-simulators  Providing good diagnostic feed-back to the user is very important, and expect well-reported issues to be fixed.

Cheers,
Alf

Emne: [Opm] OPM Query - From a New User

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,
David Wilkinson
