Hi all,
What suggestions can you provide for simulating a large domain where periodic boundary conditions cannot be applied?
If we want to simulate the pressure drop and temperature changes across a very long pipe, is there a way to break it down into sections each with a 1 meter length and simulate the first section only? How to set the boundary conditions in this case? Is there a tutorial that covers a similar concept?

Thanks!
