Hello:
I'm attempting to model flow in a simple flange assembly. The flange assembly has a pipe running through its center with a heated gas in it, and the flanges are water-cooled. When I attempt to set up a fluid subdomain within the pipe and select the lid on its end, for some reason, the fluid subdomain is only half of the pipe's volume. See the attached document for pics.
However, if I model a simplified part version of the total assembly, and construct a fluid subdomain, the subdomain takes on the complete volume of the pipe like it is supposed to.
Being new to Flow Simulation, I've never run across this before. Can someone explain why this is happening, and how I can correct this problem?
Thanks.
Marty
my guess would be you have a hidden part that is active or your computational domain has a boundary there.
