Stan Zhou Member Haoran Zhou Join Date: Nov 2019 Posts: 49 Rep Power: 7	Hi all, I'm doing wave structure simulation using OpenFOAM. I extracted pressure time series of several monitoring points on the structure and found one of the time series had some negative pressure. I did another simulation with refined mesh to perform mesh convergence check and found some of the negative pressure disappear. Can I come to the conclusion that the previous negative pressure are due to the nonconvergence? And the left negative pressure are caused by wave retreating?
