Sets the initial condition for a 2D Riemann problem in terms of 4 four constant states at each corner of the computational domain.
For example, the top right corner, ,
, is denoted with
PP
and its initial values are:
Similar conditions hold for the bottom right corner ( ,
;
PM
), the top left ( ,
;
MP
), and the bottom left ( ,
;
MM
). The 4 flow quantities of each corner are defined by the 16 parameters that are read from pluto.ini.
