Detailed Description

Class implementing the quantum van der Waals model in the strangeness-canonical ensemble.

NOTE

The calculations are approximate and assume that strange particles form a small part of the total system, i.e. their contribution to the total density/pressure is close to negligible. Calculations may not be accurate if this condition is not fulfilled.
