Hello all,

I am looking for how to assure that one and only one fluid is used.  For
instance, in the following snippet, "ifield" should not be greater than
1.  I guess am not sure what "ifield" means exactly.

      if (ifield.eq.1) then ! fluid/gas
      
         utrans=param(1)    ! density of liquid
         udiff =param(2)    ! dynamic viscosity of liquid

      else                  ! Thermal properties

         utrans=.1*param(7)    ! rhocp, liquid
         udiff =.1*param(8)    ! conductivity, liquid

      endif

Cheers,
Frank
