Surface Tension - VOF

Diconico · August 27, 2020, 13:59

Hi everybody!

How fluent computs the smoothed volume fraction field for the curvature calculation in VOF?

I've seen that changing the parameters in:
solve/set/surface-tension

regarding the number of smoothing and the smooth relaxation affects the results, but there is none information in the guide, or in articles regarding the equations used for this and how the adopted values affect the calculation!

It seems that there are a lot of models that can perform this smoothing, but how fluent does it? There is a way to know?

Hi everyone, I have the same question as Diconico. Diconico, did you find a solution?
