HORSES3D uses a high-order discontinuous Galerkin Spectral Element (DGSEM) method. As part of the numerical method, several options of volume and surface discretization options can be selected. Some options are only available in certain solvers.

|---|---|---|
| Discretization nodes | CHARACTER: Node type to use in the solution. Options are: - Gauss - Gauss-Lobatto |
'Gauss' |
| Inviscid discretization | CHARACTER: DG discretization of inviscid fluxes. Options are: - Standard - Split-Form |
'Standard' |
| Averaging | CHARACTER: Type of averaging function to use in numerical fluxes and split-forms (if in use). Options are: - Standard - Morinishi - Ducros - Kennedy-Gruber - Pirozzoli - Entropy conserving - Chandrasekar - Skew-symmetric 1 (only for Incompressible Navier–Stokes) - Skew-symmetric 2 (only for Incompressible Navier–Stokes) |
