      You can use a junction box, which writes the actual values of the viscosity into the MMS at the end of the coefficient loop. You can also use a user cel routine, which reads the viscosity values out of the MMS and stores it as an Additional Variable (AV). This AV is used as viscosity of the old iteration in the expression for the viscosity.
