First paper on Ocellaris has been published

The first paper 1 on Ocellaris has between accepted for publication in Computers & Fluids. The paper describes the slope limiter used to stabilise the velocity field with regards to the instabilities that occur near the jump in density between the two phases. The paper describes the limiter and shows the applicability of the method to simulate air/water flows in 2D.

The paper is available online at DOI 10.1016/j.compfluid.2019.104322, though it may take some days before the pre-print version is replaced with the final version.
