Detailed Description

Class collecting simple pvt properties for 1-3 phases. All phases are incompressible and have constant viscosities. For all the methods, the following apply: p, T and z are unused. Output arrays shall be of size n*numPhases(), and must be valid before calling the method. NOTE: This class is intentionally similar to BlackoilPvtProperties.
