<P><FONT SIZE=2>Hi.<BR>
How can not think of any obvious reason for this.<BR>
How did you measure that - especially comparing the performance<BR>
of that one method between different grids? What did your test code look like<BR>
and which codimension did you test?<BR>
<BR>

Subject: [Dune] accessing the subIndex on 3D elements using ALUGRID<BR>
<BR>
Dear Dune,<BR>
<BR>
I would like to ask one question about accessing the subIndex routine in<BR>
ALUGRID:<BR>
Observed that accessing the subIndex routine is slower(at least 40%) in ALU<BR>
comparing with UG or YASP.<BR>
This is only in 3D and it is fine again in 2D. Accessing the function looks<BR>
as follows:<BR>
indexset.subIndex(*it,i,dim);<BR>
Is it a open issue in ALU grid (only for 3D elements) implementation or I<BR>
made a mistake while ALU grid installation?<BR>
I am using the latest svn version of DUNE and ALU-1.50.<BR>
<BR>
I wish you a merry Christmas and happy new year.<BR>
<BR>
Best Regards<BR>
Nagaiah<BR>
