Detailed Description

The Arrhenius temperature-dependent viscosity model multiplies the viscosity of a base model by an Arrhenius-type temperature function:

mu = mu0*exp(k1*(1/(T + k2) - 1/(Tref + k2)))

Where: mu0 is the base-model viscosity k1 and k2 are Arrhenius coefficients T is the local temperature Tref is the reference temperature
