As for case 150, but with the Prandtl 1-equation model.
ENDDIS
The locally-defined variables are as follows:
EPSIN The dissipation rate at the inlet
GMIXL The length scale at the inlet
REAL(EPSIN,GMIXL)
GROUP 7. Variables stored, solved & named
SOLUTN(EP,Y,Y,N,N,N,Y)
GROUP 9. Properties of the medium (or media)
** Select k-e Length scale formula
EL1=KE15DEP;ENUT=PRKOLM
GROUP 13. Boundary conditions and special sources
COVAL(HIGHY,EP,ONLYMS,1.E-6)
COVAL(OUTSIDE,EP,ONLYMS,1.E-6)
