How do I construct a non planar lid aroung a circular surface with flow outlet slots?
I never use the automatic lids (old dog, new tricks), and in this instance it seems simplest to simply make a dummy body to act as your lid so you can use whatever shape suits your needs.
When i draw a circular band using the feature manager and then specify the inside surface as a outlet boundry in flow simulation I get an error message. There are three slots in the valve cylindrical body that the band covered. I have tried makin the band end at the OD of the cylindrical body, plus, have it extend a couple of thousands into the slots. Still get the same error not lying on a boundry between a solid or liquid region.
can you post a picture of it? I'm in 2007 so you'd have to .step it out, but a simple .jpeg might be enough to help explain
It is like a cartridge valve with outlet holes/slots on the cylindrical valve body. Cannot provide you the model as it is proprietary.
so something like this?
If the port exits the curved face you should still be able to create a mating curve solid and use that as the boundary
thats what I tried to do.
then there's likely a hole someplace in the model, otherwise this should work. Have you tried checking the geometry and having it make a fluid body assembly? This will often show you were the issue is.
Another solution is to temporarily set it as an external simulation, add a huge inlet flow, start the simulation and let it run a few cycles, then stop it and look for the high velocity at your leak.
