I'm new to flow simulation and I have gone through a lot of examples and I'm getting a grasp on how effective this tool can be.
I have a few questions that maybe some of you could help answer.
I have some images here of my project that I'm working on. I am creating a flow study that has time dependancies. The inlet flow rate is what I will be changing over time.
I have found where I can specify either an equation or a table of values for flow rate as a function of time. The main problem I'm running into is that I need to specify a back and forth cyclical flow from +30 ul/s to -30 ul/sec. Using the table, it will not accept negative values for flow rate (which I guessed it wouldn't but I tried anyway).
How can I create boundry conditions that will allow back and forth flow? As you can see from the image above (or not due to resolution) I have a flow cycle period of 3 cycles / 5 seconds.
Thanks in advance for any help
