  We present the latest developments of our High-Order Spectral Element Solver
(HORSES3D), an open source high-order discontinuous Galerkin framework, capable
of solving a variety of flow applications, including compressible flows (with
or without shocks), incompressible flows, various RANS and LES turbulence
models, particle dynamics, multiphase flows, and aeroacoustics. We provide an
overview of the high-order spatial discretisation (including energy/entropy
stable schemes) and anisotropic p-adaptation capabilities. The solver is
parallelised using MPI and OpenMP showing good scalability for up to 1000
processors. Temporal discretisations include explicit, implicit, multigrid, and
dual time-stepping schemes with efficient preconditioners. Additionally, we
facilitate meshing and simulating complex geometries through a mesh-free
immersed boundary technique. We detail the available documentation and the test
cases included in the GitHub repository.
