Hey Amir,<br>
<br>
is this happening on the master branch of dune-uggrid/dune-grid/dune-pdelab<br>
or on a release branch?<br>
Please make sure that you are using consistent branches and report which<br>
one you are using.<br>
If the branch is master, it would be very insightful if you could try the<br>
releases/2.7 branch as well.<br>
There were changes in dune-grid regarding UG's capabilities that have<br>
caused similar issues before.<br>
<br>
Best,<br>
Dominic<br>

Hi Amir,<br>
to me this looks like dune-grid is not build with UGGrid<br>
support. To do so, you need to build dune-uggrid before<br>
dune-grid. Simply using dunecontrol will do all of this<br>
in the appropriate order. I suspect that you've first build<br>
the core-modules (including dune-grid) and later added<br>
dune-uggrid which may explain the problem.<br>
<br>
If that's the reason, simply rebuilding dune-grid should<br>
solve the problem.<br>
<br>
Best,<br>
Carsten<br>
