[Nek5000-users] PN field to PN-2 field

[nek5000-users at lists.mcs.anl.gov]

Hi Vincent,

It looks like the routine map12 will do this.
It's to be called on an element by element basis --- thus:

       integer e
       do e=1,nelt
          call map12(b(1,1,1,e),a(1,1,1,e))
       enddo

would yield the desired result.

May I inquire as to the application?  (There are times when
it might be better to use the transpose of the interpolation
operator.)

Paul
