Patch application in VOF model
Hi everyone,
I have a problem when I use Patch in VOF and hope someone could clear my doubt! The problem is as follow: The model has two phases- one is oil and another is water. I hope to simulate the process of the two phases flowing a cylinder. I initialized with water(primary phase), then checked the contours of volume fraction, and can see a whole pipe of water. Then I patched oil to the inner part of the pipe, hoping get an initialization of oil core surrounded with water. But after the patching, I checked the contours of volume fraction again. The contours didn't show an oil core surrounded with water, but whole section of oil. I tried several times, still the same results. I wander does the contours indicate that the patching is not applied successfully or it does applied successfully but the contours don't update after the patching? Kind Regards, Jing |
Contours updates after patching. Something is wrong when you are patching for oil. How are you selecting the region? Region>mark?

Hi Shikamaru,
Thanks for your reply! I found the problem now. I did use the Region>mark. But the mistake I made is that when I selected the Patch Region, I not only selected the register but also selected the Zones to patch, which made the whole piped patched with oil! But if I adapt a cylinder region, and mark it, is it true that the registered cylinder region is not exact the same as what I defined. I found the marked cylinder is slimmer near inlet and outlet. |
