I am trying to select an inner face in order to apply a boundarycondition in Floworks, but there does not seem to be a face toselect. Is it possible to create a face? I have cycled through allthe faces on the model but the one I want does not exist. Any helpwould be appreciated thanks./
To analyze just internal flow you need to define caps/lids for theentry and exit areas (so that it is a fully enclosed volume). Thisis best done through adding additional parts/bodies. In 2008 thereis an "autocapping feature" but I have not tried it in awide variety of situations to have a good feel for how itperforms.
Remember that you need to make sure the caps do not form a poorcontact(e.g. 2 solids just touching just along an edge). They needto seal the internal volume (solids that overlap work well). Thereis information on this on the online help (which is prettycomprehensive). I'd also recommend doing the supplied tutorial forinternal flow (ball valve design).
Hope this helps you out.
Cheers,
Ian
