Pretty big case you have hear for this kind of equation. Could you comment a little bit how the number of iterations grow with the problem size. I guess you are using diagonal preconditioner and some Krylov method.

PS. Happy holiday season. I expect it will be quite little traffic here and possible questions may ave to wait to get an answer.

Hi,
yes it is a big case (linear luckily) and you are right I use BiCGStab but without preconditioning. I didn't see any major increase in iteration count when increasing from 150k to 1.5M elements. Seems to be very robust solver.
Cheers,

ps. Speaking of holiday season: I caught an influenza virus presumably on the 22nd of December and had a complication meaning that I have been sick from 24th of December until now... Luckily I'm feeling better now that I start working tomorrow Life is great sometimes!
