abdoganawa is on a distinguished road
Actually I used VOF to simulate slug multiphase flow (air - water ) in pipe, initial volume fraction distribution for the both phases is (.5,.5), the velocity for water 1.8 m/s and 1 for air, I supposed to use field function to define that as follow:
for water ($$Centroid[1]<0 -> 1.8) and for air ($$Centroid[1]>=0 -> 1,0,0). then the problem how I can compile them (my pipe with one inlet and I don't want to use mixture model).
also I want to put a condition that the water velocity = 1.8 when V F =1 other than that the water velocity =1.2 ($VolumeFractionWater=1?1.8:1.2)

regards
