<P> </P>
<P>I have a question about this routine. I haven't tried this yet, but I am curious if the "overall domain" </P>
<P>of the new mesh needs to be exactly the same as the old mesh? Or if you can remove a portion of </P>
<P>the domain completely, but still use g2gi to interpolate onto the new, remaining mesh? </P>
<P> </P>
<P>Thanks for any info!</P>

<DIV><BR></DIV>The g2gi() routine can be used to interpolate an existing field file onto a new mesh - so it will do exactly what you want to do.

<DIV dir=ltr>Hi,
<DIV><BR></DIV>
<DIV>Recently there was an updated routine in nek called grid-to-grid interpolation (g2gi). I tried to understand it by grepping to source code, but couldn't make much sense out of it. Could anyone brief what it is it for ?</DIV>
<DIV><BR></DIV>
<DIV>I have a nek simulation in which I have got lots of data, but for some comparisons, would like to do a grid refinement (quad/oct from prenek) and restart from the existing field files if that is possible. I know that for h-type refinement, usually the simulation has to be started afresh. But I was wondering if g2gi would make it possible to restart from a previous simulation.</DIV>
<DIV><BR></DIV>
<DIV>Thanks</DIV>
