Hi,<br>
I guess the question is whether there is a similar type of Uzawa<br>
iteration also for Pnpn, this I don't know and I have not looked into<br>
the theory. I can only say that for PnPn-2, with the nested iterations<br>
you can get a perfect pressure (i.e. not proportional to Delta p) in one<br>
time step. I guess one needs a PnPn user to answer that question.<br>
<br>
Just as a side question; why do you want to go from PnPn-2 to PnPn? Out<br>
of curiosity...<br>
<br>
Best regards,<br>
PHilipp<br>
