Thanks for testing Rohith, we will need to find time to go through your cases.
Cheers,
Alf

Hi Alf,
The switch linear_solver_ignoreconvergencefailure=true doesn’t seem to help in
this case.
Additionally, a deck file
(https://gist.github.com/nairr/8dbe35141a7b93dda90a1babd462b843 ) which used to
run with FLOW_2016.04_stablerelease, gives the following error with
FLOW_2016.04_current: Floating point exception (core dumped). I think the same
issue has been referenced in opm-simulators #731.
Cheers,
Rohith

Hi Rohith,
One thing you can try right away is the new switch for ignoring convergence
failure for the linear solver. On the command line or in a parameter file you
can add:
linear_solver_ignoreconvergencefailure=true

Subject: [Opm] FW: [Help] Convergence issues - FLOW
Dear OPM community,
At the recently held OPM meeting I had mentioned that we at TNO are facing
convergence issues with FLOW when using perturbed schedule files and also with
handling well openings (Note: ECLIPSE is able to deal with these perturbed
schedule files). I believe it was mentioned that you guys were already working
towards a fix for these sort of issues. We would appreciate your
help/suggestions/workarounds in solving these convergence issues and ultimately
improving the robustness of the FLOW simulator in the process.
Please find the relevant data available for download from the following link:
https://we.tl/OBTYWPLnwg
The download contains:
1. Failed simulation with FLOW for simple water injection rate
optimization (successful simulation is also included): The only difference
between the successful and failed simulation is different water injection rates
2. Failed simulation where wells are opened at predefined intervals
3. Benchmark plots which successfully compare FLOW with other
simulators(E100, MRST, Mores, AD-GPRS) for oil-water flow simulation
Thanks and Kind regards,
Rohith Nair
