Separates the ModelerGeometry object into an array of solids representing the additional disjoint volumes. This ModelerGeometry object is reduced to a solid with one volume. 

eOk if separating was successful or an appropriate error code otherwise.

The calling application is responsible for the resulting entities (either appending them to a database or deleting them when they are no longer needed). If the new solids from the output array are not appended to the database and not deleted, there will be a memory leak.
