Volume fraction residual does not appear on residual plots on using VOF explicit. Why?

Hi,

Check solution - controls - equations then check volume fraction is selected.

Hope this helps you.

VOF equation is checked. 

This is happening only with VOF explicit. Please see below image

Hi,

Explicit formulation does not require iterative solution of the transport equation during each time step, as is needed for the following implicit scheme. Thats a reason, it is not showing.

Hope this answers your question.

I did not get this. Can you please explain in detail?

Hi,

For detail explanation, I suggest you to please check ansys theory guide where it has explained in details along with the equations involved. 14.3.4. Volume Fraction Equation (ansys.com)

Hope this helps you.
