Ocellaris and my PhD project

Ocellaris, the free surface two phase Navier-Stokes solver I have been building as a part of my PhD work at the Department of Mathematics at the University of Oslo is finally ready for the world! It is built using an exactly divergence free unstructured DG FEM numerical method that uses special velocity slope limiters to stabilise the higher order shape functions near the factor 1000 jump in momentum at the air/water free surface, which enables higher order simulations of free surface flows such as ocean waves. I just released version 2019.0.1, which has greatly improved the user guide and general documentation.

You can see an example simulation below, more examples are available on the Ocellaris Blog.

The PhD thesis and the included papers are all soon ready as pre-prints. Looking forward to delivering this winter!
