The log of the valgrind is attached. When I run with valgrind, the
following error message comes up.<br>

I try to use the block matrix (BAIJ) for the dmplex data
structure with the option "-dm_mat_type baij" (the block
size is 7). The code works fine when np = 1 but the
following error comes up when np>1. And the code also
works fine for np>1 if I set the block size to be 1. Any
suggestions are highly appreciated.<br>
