UDF for dynamic contact angle

Aireen

Can somebody help me. I wrote a simple udf to specify dynamic contact angle in VOF model. When I hook it up, it didn't report any error. But the result from the simulation was not what I expected. This is my code:

DEFINE_PROFILE(contact_angle,c, mixture_thread) { real theta; real current_time = CURRENT_TIME;

if (current_time <= 0.003)

theta = 140;

else

theta = 14;

}
