</span>This only happens if the information in the RemoteIndices is not in<br>
sync with the underlying IndexSets. This can be case if these were<br>
changed, but there was not call to RemoteIndices::rebuild().<br>
Thi is also reflected in the error message: "RemoteIndices is not in<br>
sync with the index set. Call RemoteIndices::rebuild first!"<br>
<br>
So the question is: How do you set up the index sets and the remote<br>
information that you are using in OwnerOverlapCopyCommunication?<br>
<br>

Do you need more support with DUNE or HPC in general?<br>
