thanks ben,
in
exodusII_IO::read
the element subdomain_id gets set to the block id
elem->subdomain_id() = subdomain_id;
using cubit you can also set two groups of same types of elements
with different block ID. Not really a problem, but does
MeshBase::n_subdomains()
affect the mesh partition later on or anything?
Would it cause any problems
if the corresponding variables of
ExodusII::get_num_elem_blk() & MeshBase::n_subdomains()
were set equal?
