Here is the code to delete a discrete element :

***************************************************************************
ElementDestroyer::ElementDestroyer() : StandAloneEngine()
{
    ballId = 1;
    iterDestroy = 0;
}

ElementDestroyer::~ElementDestroyer()
{
}

void ElementDestroyer::registerAttributes()
{
    StandAloneEngine::registerAttributes();
    REGISTER_ATTRIBUTE(ballId);
    REGISTER_ATTRIBUTE(iterDestroy);
}

bool ElementDestroyer::isActivated()
{
    return ( Omega::instance().getCurrentIteration() == iterDestroy);
}


void ElementDestroyer::action(Body * body)
{
    MetaBody * ncb = dynamic_cast<MetaBody*>(body);

    BodyContainer::iterator bi    = ncb->bodies->begin();
    BodyContainer::iterator biEnd = ncb->bodies->end();
    for(  ; bi!=biEnd ; ++bi )
    {
        shared_ptr<Body> body = *bi;
        if (body->getId() == ballId)
            ncb->bodies->erase(body->getId());
    }
}
***************************************************************************

Have a good day
