Droplet generated in T-junction disappeared along the channel

Please login with a confirmed email address before reporting spam

Hi, I have been trying to run simulations to generate droplets in t-junction microchannel. I succeeded in generating a droplet(slug flow type) but along the channel, it started shrinking and disappeared completely before reaching the outlet. I haven't seen anything like this before,like if the fluids are immiscible how can a full droplet vanish!!?. Flow conditions-: qc=qd=100nl/min Wetted wall condition with contact angle= -pi/4 surface tension=0.0025

Also, after this simulation, I have been getting lots of '-out' & the following warning in the log window-: "Warning: Problem encountered during results while solving. Unexpected size of render data."

It would be really wonderful,if someone can suggest a solution to fix this problem
