Hello everybody

In gammaEqn.H of interPhaseChangeFoam solver we have these lines:

volScalarField Sp
vDotvAlphal - vDotcAlphal
volScalarField Su
+ vDotcAlphal

MULES::implicitSolve(oneField(), gamma, phi, phiGamma, Sp, Su, 1, 0);

why isn't Sp zero, if the equation to solve (MULESTemplates.C) is this:

d(1*psi)/dt + div(phigamma) + Sp*gamma - Su = 0

Is Sp different from zero to improve convergence? Or what?
