CINT

------ PIL real array; default=1.0; group 10,

CINT(phi) concerns inter-phase diffusion in two-phase flow simulations.

If CINT(phi) has a positive value, the bulk-to-interface diffusion coefficient for the variable phi is equal to that value times the reference interface coefficient set by way of CFIPS.
It is in this case a dimensionless multiplication factor.

If CINT(phi) has a negative value other than GRND or GRNDx the bulk-to-interface diffusion coefficient for the variable phi is equal to the negative of that value.
Its dimensions are then transfer rate per unit volume divided by phi-difference.

If CINT is set equal to GRND, EARTH calls GROUP 10 of GROUND, where it expects to find an array of interphase-coefficient values computed by coding introducd by the user.

If CINT is set equal to GRNDx, EARTH calls the open-source subroutine GXIDIF, where the following options are supplied by CHAM:
