rgfrosh.shock

The core functionality of rgfrosh is built on the Shock class, which defines the state of the different regions of the reflected shock. Shock is a frozen data class - its attributes cannot be assigned after instantiation - and thus it is not very useful to instantiate it directly. Two different models are defined to calculate shock conditions:

• Ideal shock - the analytical solution of the conservation equations for ideal (calorically perfect) gases.
• Frozen shock - a numerical solver for a gas with an arbitrary equation of state.
