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>
