Zero viscosity udf-fluid??

I run a simulation of 2D application using vof model and a udf for the viscosity but the fluid "acts" as a zero viscosity fluid. (flows very fast)
When i go to contours viscosity value is 0 for the second phase (which is the udf fluid).
Can anyone help me please?
The udf code is:
real mo=80; real m=1000;
strain_rate = C_STRAIN_RATE_MAG(c,t);
mu_lam = mo + to*(1-exp(-m*strain_rate))/strain_rate;
Thank you in advance.
(i post it here too, as udf questions it isnot the common practice sorry admin)
