[solver-interfaces]

Parameterises the interfaces with

1. riemann-solver — type of Riemann solver:

   rusanov | hll | hllc | roe | roem | exact

   where

   hll | hllc | roe | roem | exact do not work with ac-euler | ac-navier-stokes

2. ldg-beta — beta parameter used for LDG:

   float

3. ldg-tau — tau parameter used for LDG:

   float

Example:

[solver-interfaces]
riemann-solver = rusanov
ldg-beta = 0.5
ldg-tau = 0.1
