Steady state at vof!!
 

I wanted to know if we can get steady state, in vof or not, I mean in the steady state condition, should the flux net of the field equal to zero or not? NOTE :The initial condition and all the boundaries of the unsteady state are known.

Re: Steady state at vof!!
 

Yes, you can get steady state at VOF. You should use the implicit scheme in VOF model. You will get the flux net.

I have used this implicit scheme, but the final net flow rate is not equal to zero.

How did you calculate the net flow? Net flow of which fluid?

net flow rate calculation is done by program.

Re: Steady state at vof!!
 

Yes for steady state, the net flux is zero, if not, your solution is not converged assuming that your program is correct.

For unsteady state, [Total accumulation+initial mass=total input of mass-total output of mass] for that time. If not, your program is wrong/ solution didn't converge.

Hope this helps.

What do you mean by accumulation.. this sumation is calculated on what... thanks
