<p>Dear Vatslav,</p>
<p><br>
</p>
<p>It's not clear to me how your approach should function if your intent</p>
<p>is to change a Periodic BC to an overlapping-domain-interpolation one.</p>
<p><br>
</p>
<p>I guess what you are trying to do is to have one domain that is periodic</p>
<p>and use that to drive the flow in another domain, which is presumably</p>
<p>inflow-outflow? If that is your goal, you might find that recirculating BCs</p>
<p>would be of value (possibly a bit more efficient), depending on your setup.</p>
<p><br>
</p>
<p>If we understand the objective we might be able to help.</p>
<p>Best,</p>
<p>Paul</p>
<p><br>

<div>Hi, Neks.<br>
<br>
</div>
I use neknek script in my simulation. I write the function like set_intflag in multimesh.f to find special bc and mark it:<br>
<br>
nfaces = 2*ndim<br>
nel = nelfld(ifield)<br>
<br>
nflag=nel*nfaces<br>
call izero(intflag,nflag)<br>
<br>
do j=1,ifield<br>
do e=1,nel<br>
do f=1,nfaces<br>
if ( session.eq.'pipe_per1' ) then<br>
if ( cbc(f,e,j).eq.'P ' ) intflag(f,e) = 1<br>
endif<br>
<br>
if ( session.eq.'pipe_per2' ) then<br>
if ( cbc(f,e,j).eq.'v ' ) intflag(f,e) = 1<br>
endif<br>
enddo<br>
enddo<br>
enddo<br>
<br>
</div>
( from periodic bc in one nek-session to inlet bc in another nek-session ).<br>
<br>
</div>
So, it works very well on old version of nek, but on the latest version of Nek5000 i can't interpolate boundary slice between two session in such way anymore. And I absolutely no idea why.<br>
<br>
</div>
Can anyone say how it can be fixed?<br>
