Hi, thanks for the video. I want to know how to display the full simulation as at the beginning of the video, for the full volume, not just through the symmetry section.
There is a mirror option that you can select. If it does not show up as an option sometimes the issue can be that in the beginning you did not set up the surface a symmetry boundary.
@@EngelUniverse Many thanks for your reply, actually I applied your steps on another geometry, the geometry which I applied is not symmetrical. I want to show the results as a video, like the one you shared at the beginning of this tutorial. How can I do this?
Hi and thanks for your useful tutorial. I have a question regarding the flow in & flow out. Is there a possibility to simulate an imaginary inlet valve and close it after a particular time while an imaginary outlet valve is still open? My goal is to observe how the rest of the simulation will be continued just when the existing fluid in the tank flows out? For instance, the water flows in for A seconds while the whole simulation is run for A+B seconds. So the inlet flow is stopped after A seconds, while the simulation will be continued for the B second. I hope I could have expressed my mean. Thanks in advance for your response.
I haven't done anything like that yet, but I beleive the way it is done is that instead of putting in a constant value for inlet or outlet, you enter a particular function. You need to create a function that allows the value to behave in a way a valve would; like for example, after a certain time its value would go down to zero. This way you would simulate the instance where the valve get closed.
Could you explain cell zone and outlets conditions? Cloud you tell value of Operating Pressure? What value of Gauge Pressure on outlets? Thank you for usefull video!
Cell Zone condition was automatically assigned in this problem by Ansys. Usually it does a good job assigning it, but I just like to click in there and visually verify that what I'm seeing is actually acceptable for my physics setup for the problem.
Make sure you set up all inlets and outlets correctly at the Boundary Conditions section, and then when you initialize, it will automatically initialize all of them. You don't need to initialize each of them separately.

Thanks so much for posting this, helping me a great deal with my uni project!
Glad I could help!

@@EngelUniverse Thanks for your time and explanation. I will follow your instruction. Cheers.

What solution method did you use - Simple or Coupled? For the outlet boundary condition, is the volume fraction for water 0 or 1?
Solution Method was Simple. About the volume fraction, sorry but I don't remember the settings
@@EngelUniverse Thanks for your reply. I'm trying to create a multiphase model using VOF and am using the Simple scheme too.
Nice explanation. Please make a video on volume of fluid setup for direct methanol fuel cell.
Since I specialize in heat transfer, I think that is a bit out of my expertiese!
@@EngelUniverse ohk, can i get your email id?
You can reach me here anytime!
How initialize calculation when chamber has 2 inlets?
Make sure you set up all inlets and outlets correctly at the Boundary Conditions section, and then when you initialize, it will automatically initialize all of them. You don't need to initialize each of them separately.
@@EngelUniverse Thank you.
