Hi, Karl,
I did not see any convergence problem with Bw to be 0.8, 1.0 and 1.2.
I assume Bw is the second term in the keyword PVTW .
Which version of OPM are you using?
I attached the DATA file I am using and I only adjusted Bw value in
PVTW keyword for testing.
I am not that familiar with the purpose of the experiments and I am
not sure what kind of effects that Bw can make here.
With Bw to be 0.8,
