Hi all,
I've been trying to simulate water & air flow past a yacht in a domain with an initialed volume of fluid, as illustrated below. However, when I simulate this I get peculiar behavior at the inlet patch, wherein the water seems to climb the boundaries of the domain in the opposite direction of fluid flow, as shown below. I've taken the yacht out of the simulation in an effort to speed up simulation times while I rectify this. I've tried altering patch types, positions (i.e. the air inlet/outlet being the top surface opposed to the side surfaces), differing flow velocities, and initializing the volume of fluid with a uniform velocity matching the inlet boundary condition. All of my simulation iterations seem to demonstrate the same behavior. Is anyone able to offer any suggestions on how to correct this? I've attached my case below for your reference. https://drive.google.com/open?id=1hF...KbXubSQNJMM3a_ Thanks and best regards domainSetup.png problem.jpg |
