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: #include"udf.h" DEFINE_PROPERTY(viscosity_model,c,t) { real mu_lam; real strain_rate; real to=80; 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; return mu_lam; } Thank you in advance. ![]() |
