Hi everyone,

I obtained a unstable RMX residual graph after 1000 iterations at levels 1e-5 residual. i've attached an image of residual graph.

By unstable i mean, towards the end of the calculation, the residual graph for all residual variables are almost sinusoidal, not a clean stable line.

I think this unstable line in residual graph is of some concern, but how concern should i be please? What can i do to eliminate this unstability please?

Look forward to hear of any comments/suggestions.
