FlowingLiquid Viscosity Card EPOXY

[wortiz]

Developer: Kristianto Tjiptowidjojo
Description: Add epoxy curing model to the increase of FlowingLuqid Viscosity in
Brinkman term of momentum equation. The functional form is the same as EPOXY
model in Liquid Constitutive Equation
Example: FlowingLiquid Viscosity = EPOXY {mu0} {alpha_g} {A} {B} {Aexp} {species_num}
mu_0 is viscosity at reference, i.e. unreacted, state; alpha_g is extent
reaction at gel point;
A and B are exponents of extent-of-reaction dependence;
Aexp is the exponent of thermal, i.e. Arrhenius, dependence;
and species_num is the species index in integer that track the extent of reaction
in the species equation
