Dear Vatslav,


It's not clear to me how your approach should function if your intent

is to change a Periodic BC to an overlapping-domain-interpolation one.


I guess what you are trying to do is to have one domain that is periodic

and use that to drive the flow in another domain, which is presumably

inflow-outflow?   If that is your goal, you might find that recirculating BCs

would be of value (possibly a bit more efficient), depending on your setup.


If we understand the objective we might be able to help.

Best,

Paul

Hi, Neks.

I use neknek script in my simulation. I write the function like set_intflag in multimesh.f to find special bc and mark it:

      nfaces = 2*ndim
      nel    = nelfld(ifield)

      nflag=nel*nfaces
      call izero(intflag,nflag)

      do j=1,ifield
      do e=1,nel
      do f=1,nfaces
        if ( session.eq.'pipe_per1' ) then
          if ( cbc(f,e,j).eq.'P  ' ) intflag(f,e) = 1
        endif

        if ( session.eq.'pipe_per2' ) then
          if ( cbc(f,e,j).eq.'v  ' ) intflag(f,e) = 1
        endif
      enddo
      enddo
      enddo

( from periodic bc in one nek-session to inlet bc in another nek-session ).

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.

Can anyone say how it can be fixed?

Regard, Vatslav
