It does not seem you are attempting to use large blocks, but the
problem likely is computing block geometry in the case the mesh is
deeply nested. 2^30 factor is pretty big and a loss of accuracy is
nearly inevitable in this case since Paramesh operates on real,
physical coordinates. Remove a few refinement levels and see if
the problem goes away.<br>
<br>
So my feeling is that this is not the interpolation package
itself. :-)<br>

Multidimensional conservative mapping is
complicated. The original package came from NCAR,
and adapting and extending it to the needs of hydro
applications (first AMRA, then FLASH) was quite an
adventure.<br>

I have seen this kind of error ages ago. It means that
coordinates are non-monotonic. The most likely cause
is <tt><tt>the geometry of your blocks is not passed
correctly to the mapping package.<br>
<br>
</tt>What is your setup line? Some memory-related
entities are hardwired and you might simply be
exceeding those limits.<br>

<div>I've been tracking the error down a bit
more, here's what I can add.<br>
<br>
</div>
The call for Driver_abortFlash is coming
from amr_prolong_gen_unk1_fun.F90 which is
trying to call the umap3 subroutine in umap.F
(for interpolation between different sized
grids?). Error 421 specifically states in
umap3:<br>
<br>
ier = 421<br>
do ii = 2,mx<br>
if ( xx(ii-1).gt.xx(ii) ) return<br>
end do<br>
<br>
</div>
There are a LOT of variables in this subroutine,
and its a bit hard to follow what this is
checking. So I'm having trouble parsing out much
past this point. I might add that these runs are
across multiple nodes on a Beowulf cluster (the
first I've attempted like this) and its the
first time I've seen this error. Oddly enough,
my first run was fine until I got a hang during
a refinement iteration (probably because I
either ran out of processors or memory). Then
when I tried to make a few changes to add some
procs, I have gotten this error. Any help would
be greatly appreciated.<br>

I'm receiving an odd error from FLASH
and I'm not sure how to interpret it.
Perhaps someone can enlighten me? Its:<br>
<br>
**ERROR** - ierr from UMAPn is
421 , isg= 4<br>
DRIVER_ABORT: ERROR - ierr from UMAPn is
not 0<br>
