We are two undergraduate students seeking for help!!!
We 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.
In 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.
COULD ANYONE HELP PELASE? HOW CAN WE SOLVE IT?
THANK YOU VERY MUCH IN ADVANCE!
Hi. I see that you haven't justified your initial conditions in the code, or have you? I think justifying initial parameters within the code would be better.

Hello Lídia Martínez-Dalmau ,
first thing I see is a missing " charackter behind #include "udf.h ...
Furthermore, you should avoid the use of bitwise operators in place of logical operators use || and && instead.
Hope that helps.
Best regards
Christian
