Dear all,
I am trying to simulate a droplet breakup with a level set model , as a part of my project. I have used capillary number and initial length for giving the boundary condition at the inlet. I calculated velocity with capillary number formula and then , gave a uniform velocity at the inlet for continuous phase plus a zero pressure at the outlet, then I would like to give a zero pressure gradient at the inlet and a zero velocity gradient at the outlet but I don't know how I can do this I would be glad if there is a solution for the problem. I also attached the basic model here. Aabha
