I downloaded an application called gravityCurrentFoam from here https://github.com/psu-efd/gravityCurrentFoam. There is a case in the repo which simulating gravity current in a rectangular flume. In that case, there is a hole (inlet) on the bottom of the flume which is represented as a boundary with a fixed inflow velocity. Now I'm modifying that case to simulate another experiment from a paper. I deleted that boundary but still found velocity around that area. The case I'm working on is here. https://github.com/bhqasx/Learning-openFoam-case
