I'm trying to reduce cell count by reducing the
amount of model being meshed.
I've got CAD of an intake manifold consisting of
several runners pulling air from a common plenum.
At this time, I prefer to model just 1 runner,
by trimming the model where it connects with
the plenum.
Which of the following is a better way to close
the model?
1. draw a planar surface and use an absorbing BC?
2. draw a domed surface and use an absorbing BC?
3. draw a domed surface and use a mixed BC where
some percentage of the energy is reflected
and some is absorbed?
TIA
