Hello everyone!
I am modeling laminar flow through a vertical pipe whose inlet is at the base of the pipe. The outlet is normal (90 degrees) to the pipe. The pipe is vertical along the z-axis. My analysis runs without no problems if I do not include gravity effects along the z-axis. However, the simulation never converges if I include the gravity effects. What should I try to be able to get a solution that includes the effects of gravity along the z-axis?
Thank you so much for your time!!
