Hello everyone,

I am now trying to model the pressure loss in a corrugated pipe. For that, I use periodic boundary conditions with a specified mass flow rate. The issue is that the pressure drop is oscillatory. How can I obtain a more steady solution?
Tank you in advance .

The periodic BC approach will then give you the pressure loss across one bump, from the same position on two adjacent bumps.
