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
