  nWe are two undergraduate students seeking for help!!!nWe are trying to simulate a laminar flux through a 3D pipe (25 cm long, 2 cm of diameter) consisting of a multiphase flux (air and water). We want to implement a UDF for the velocity inlet consisting of several time-dependent square pulses. nIn our ideal scenario, the pipe is initially full of air and water is injected from the inlet periodically (every injection is a square pulse) and the amount of water decreases with each interval. To do so, we have written the following code, but it does not seem to work:nCOULD ANYONE HELP PELASE?? HOW CAN WE SOLVE IT?nTHANK YOU VERY MUCH IN ADVANCE!nn
