Viscosity model in the twoPhaseEulerFoam
 
2 Attachment(s)
I'm not using the kinetic theory for the solid-phase stress tensor, but I could borrow "viscosity models" used in the solver.

For the solid phase, the momentum equation is
dUa/dt = div( nuEffa*TAU) + ...
where nuEffa=mua/rhoa

I'd like to use the BirdCarreau viscosity model for mua. mua is a function of strainRate and alpha where mua_inf, mua_0, k, and n are constants.
I checked non-newtonian solver and its viscosity models, and I tried to implement the modified BirdCarreau viscosity model located in the folder:
../twoPhaseEulerFoamMod/kineticTheoryModels/viscosityModel/BirdCarreau

When I compiled kineticTheoryModels using wmake libso, it failed. Could you give me your direction or remedy? Attached are files for the viscosity model.

Whats the error message?
