[MOAB-dev] memory leak

[Iulian Grindeanu]

----- Original Message -----

| Hello All,

| I add entity (meshset) to another meshset. This generate memory leak
| according to valgrind. Pleas see attached log.

| Should I manage meshsets using childs and parents, or adding meshset
| to another meshest using add_entities is accepted by moab.

using add_entities is accepted by moab; you can use "recursive" calls after that (recursive means it will scan the sets for other sets included) this is the meaning of 
recursive flag in get_entities type calls 

I will take a look, are you sure it is inside moab? 
How much is definitely "lost"? 

Thanks, 
Iulian
