In this repository, a new real gas model for hydrogen based on the Reference Fluid Thermodynamic and Transport Properties Database (REFPROP) v10.0 is provided for the use in the simulation software OpenFOAM v2012.

In a tutorial case of the flow through a critical flow Venturi nozzle, the usage of the new real gas model is shown.

For the start of the simulation, do the following steps:
1. run `blockMesh && extrudeMesh`

2. run either:
    - `sonicFoam` or 
    - `decomposePar` and then `mpirun -np 4 sonicFoam -parallel`

For the post-processing, you might need to:
3. run `reconstructPar` (if your case was decomposed before)
