Dear all,
I have a very strange problem using the matpower function runuopf.

I launch several iteration of runuopf and one case give me a non convergent 
solution (success flag is zero).

Within my code, I save the values the runuopf function uses, so it goes:
save casefileresultsOPF = runuopf(casefile,mpoption('OUT_ALL', 0, 'VERBOSE', 0, 
'OPF_FLOW_LIM', 2)); 
So then, after the simulation ends, I wanted to see why the OPF did not 
converge, but, when I opened matlab and loaded the casefile, this one 
succeeded.... So I just did:
load casefile;resultsOPF3 = runuopf(casefile,mpoption('OUT_ALL', 0, 'VERBOSE', 
0, 'OPF_FLOW_LIM', 2)); 
But this one succeeds which is not consistent with the results I got from the 
function within the whole simulation.

Did anyone ever had that kind of problem?

Here, you can fin attached, the casefile (datacase), the results within the 
simulation, which does not converge (resultsSIM) and the results after the 
simulation, using the casefile, and which does converge (results)

Any suggestion on how to explain and/or avoid this, is wellcome, thank you very 
much,
G.D.
