This is a full description of the different modifications done to the standard 1.3.2 version for the implementation of the %$\varphi-\alpha$% model (starting from the implementation of the %$\varphi$% model) :
• resv2f.F: Sub-routine where the elliptic / transport equation for %$\alpha$% and %$\varphi$% are implemented
• the time scale definition has moved just before the definition of the explicit source term of %$\varphi$%
• the explicit source term of the elliptic variable, now %$\alpha$%, is now : W5(IEL) = - VOLUME(IEL)*(-1.0D0)
• the explicit source term of %$\varphi$% has changed.
• it now uses the explicit value of the homogeneous pressure strain %$f_h=-\frac{1}{T}(C_1-1+C_2 \frac{P}{\varepsilon \rho}) \big(\varphi-\frac{2}{3}\big)$%, stored under the variable FHOMOG
• the explicit source term of %$\varphi$% now becomes: W2(IEL)=VOLUME(IEL)*(   RTP(IEL,IFB)**COEFFP*(FHOMOG*XROM)                                                                                                                              + 2.D0/RTPA(IEL,IKIPH)*PROPCE(IEL,IPCVST)/SIGMAK*W1(IEL))
• The array W1(IEL) stores the cross gradient %$\frac{\partial \varphi}{\partial x_i} \frac{\partial k}{\partial x_i}$%
