I am having an issue in using DataOut for such vector in a parallel process. I
am attaching a MWE which captures my problem. I am encountering a segmentation
fault (signal 11).
The problem is a mismatch of expectations. Like in many other places, when you
pass a cell-based vector to DataOut, it assumes that on every process, the
vector has one entry for each active cell of the triangulation -- i.e., on
every process it is a *local* vector -- rather than a distributed vector with
one entry for each globally active cell. In other words, for cell-based
vectors, we ignore the fact that the computation might be parallel.
