Failed in getting converged for the potential calculation for the well #1607

Hi. I'm trying to run a case on flow, but have problems with gas lift. With the previous OPM version (2018.04), I was having FLO_TYPE error when specifying the ALQ in WCONPROD section (#1598), which was solved with latest version of the OPM. But with 2018.10 version, I get the following error:

Report step  0/304 at day 0/15396, date = 06-Nov-1997

Time step 0, stepsize 1 days.

Error: [/build/opm-simulators-J49W6c/opm-simulators-2018.10-rfinal/opm/autodiff/StandardWell_impl.hpp:1887] Failed in getting converged for the potential calculation for well PROD_2

The error can be reproduced by the attached deck below. Would appreciate the help. Norne_ALQ.zip

At the moment, the well potential calculation based on THP limit is not supported in a good way. For some cases, you might get a converged result, but for many cases, you will not, mostly depending on the properties of the VFP tables. The reason is that we did not have good understanding how THP/VFP works and the current version was an implementation based on the VFP curves for some specific cases.

The new development of THP/VFP related, including the well potential calculation based on THP limit, will be updated in the near future (before New Year most likely. )

Alright, thanks. Looking forward for the new update.
