Hi Mr Rob for the LES-VOF interaction, i am running the same simulations but using ELES (2m pipe RANS + 0.5 m LES + 0.5 m RANS), and it runs fine, results are agreeing with experiments.
But when i run for just 1 m long LES in the whole domain, i get this strange pressure bursts. The monitor of the oil-water interface can be seen below, it looks reasonable.
If changing the y-axis values, it will be still reasonable
Do you have any idea why this pressure bursts would happen?
For the Laminar model or the K-omega using same geometry and mesh, pressure signal was very accurate
Thank you
