We want to implement a UDF for the velocity inlet consisting of several time-dependent square pulses.\u00a0nIn 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.\u00a0\u00a0To do so, we have written the following code, but it does not seem to work:nCOULD ANYONE HELP PELASE??
