+
+The physical definition for the thermochemical nonequilibrium (NEMO) solvers is similar to the compressible solvers, but with additional parameters to specify. The free-stream values are not only used as boundary conditions for the `MARKER_FAR` option, but also for initialization and non-dimensionalization. That means even if you don't have any farfield BCs in your problem, it might be important to prescribe physically meaningful values for the options.
+
+### Free-Stream Temperatures ###
+
+Thermodynamic state is specified using the same options as the compressible solver, with the addition of the free-stream electronic temperature. This can be specified using the `FREESTREAM_TEMPERATURE_VE` option in the config file. For a free-stream in equilibrium, this is typically the same value as specified in the `FREESTREAM_TEMPERATURE` option.
+
+### Chemical Composition and Mass Fractions ###
+
+The NEMO solvers require a specification of thermochemical nonequilibrium library using the `FLUID_MODEL` option, either `SU2_NONEQ` if using the SU2 built-in thermochemical library, or `MUTATIONPP` if using the Mutation++ thermochemical library.
+
+A chemistry model, consisting of a set of flow species, thermochemical properties, and chemical reactions, is specified using `GAS_MODEL`. The names of these models are specific to the thermochemical library. If using the `SU2_NONEQ` option the choices are `ARGON`, `N2`, `AIR-5`, and `AIR-7`. 
+
+Free-stream mass fractions must also be specified in list using the option `GAS_COMPOSITION`. The mass fractions are specified as decimal values in the order of the species in the gas model. For example, an AIR-5 mixture of 77% oxygen and 23% nitrogen would be expressed as (0.77, 0.23, 0.00, 0.00, 0.00).

+## Specifying a Fluid Model ##
+
+For fluid simulations, a model defining the equation of state and thermodynamic properties of the fluid or mixture is required. This is selected using the `FLUID_MODEL` option in the config. Available fluid models in SU2 include:
+
+| Option Value | Description | 
+|---|---|
+|`STANDARD_AIR` | **Air model with ideal gas EOS** |
+|`IDEAL_GAS` | **Arbitrary fluid with ideal gas EOS** |
+|`VW_GAS` | **Arbitrary fluid with Vander-Waals EOS** |
+|`PR_GAS` | **Arbitrary fluid with Peng-Robinson EOS** |
+|`CONSTANT_DENSITY` | **Constant density** |
+|`INC_IDEAL_GAS` | **Incompressible ideal gas** |
+|`INC_IDEAL_GAS_POLY` | **Incompressible ideal gas** |
+|`SU2_NONEQ` | **SU2 nonequilibrium thermochemical library** |
+|`MUTATIONPP` | **Mutation++ nonequilibrium thermochemical library** |
+
+Some fluid models require the specification of additional parameters, with the full set of required options available in the configuration file template.
