Description
In this talk we will explore the newly developed hydrodynamic module in CosmoLattice that allows to investigate relativistic fluids in an FLRW background. We first review the hydrodynamic equations in the conservation and non-conservation form, which have been implemented in CosmoLattice in the the relativistic and non-relativistic limit. We may then have a look at the evolution algorithms and the discretisation schemes that are used. As a first application we study the production of gravitational waves from a turbulent plasma in the relativistic and non-relativistic regime. At last we will have an outlook on how this hydrodynamic module will be further developed and connected to the other capabilities of CosmoLattice.
