Can you explain your problem more?
Actually, I don't understand why you should remove and make a new pcomm to remove entities....

Hello,

I modelling crack propagation where some entities are created and
removed. I
work with parallel meshes and have problem how to clean remove ents
and resolve
shared entities.

When I remove entity I get error,
Reason: Entity should be shared but isn't.
Tri 62:
Adjacencies:
Vertex 56, Vertex 48, Vertex 102
Edge 103, Edge 101, Edge 104
Tet 361

Can you advise me how to solve this problem?

I am not sure I understand your problem.
If entities are in a set, you should remove them from the set, before deleting
the entities.
If this is too hard, when you create the set you should use the
MESHSET_TRACK_OWNER flag.
In that case, removing from the set is managed automatically when you delete the
entity (this takes more memory, and it is not turned on by default). Do you
create sets?

I am not sure about the sharing part, but I think that you would need to manage
that yourself; the distribution/sharing is resolved at the beginning;
Still, what is the scenario?
Best Regards,
Iulian


Thanks Iulian,

I have problem with sharing part. To make it work I had to create pcomm for
meshset after entities were removed.

Now I have to solve problem how to write parallel file and force moab to use new
pcomm (f.e. index 1 instead 0).

Lukasz
