Hi every body
I have 2D open channel and want to defined a groovy condition in inlet and just for water (when alpha=1) this is my velocity profile [ type groovyBC; value uniform (0 0 0); valueExpression "((pos().y-y0)<=(A*cos(-w*time()+pi/2.0)+0.5*k*A*A*cos(2*(-w*time())+pi))) ? 1*A*w*pos().y/y0*vector( cos(-w*time()+pi/2), sin(-w*time()+pi/2), 0) : vector(0,0,0)";] with this profile the effect of an air is above the water is similar a wind that i dont want it is it possible to change velocity profile or other things to defined the velocity profile just for alpha=1?:confused: |

fractionExpression "alpha1>0.5"; or something similar should do the trick |
