Hello
Please I need help with my simulation. I simulating the rise of Taylor bubble in vertical pipe. I patched the initial bubble shape in the tube. I am using the VOF method under laminar regime. My problem is, I am not seeing any visible movement in the bubble, rather it disintegrates at the nose and wake regions. How can I fix this? Your help would be appreciated. Thanks

have you set the gravity for the vertical axis? can you include an image of your patched model?

I am unable to attach an image, but after a number of iterations, the bubble starts to split into two along the axis. I will keep trying to attach the image, that will make things clearer. Thanks
