Inconstant Surface Tension on Interface in VOF
 
I have a project which I must use VOF method for it, but the surface tension coefficient has two different values on the interface. How can I determine surface tension coefficient on different parts of interface? Can I write a UDF for it?

Surface tension coefficient can be made variable using a CEL expression.

Real VOF is not possible using CFX. Go to Fluent or STAR CD.

What Astrid meant to say is "Reconstructing Volume Tracking" is not available in CFX.

The interface capturing in CFX is pretty good.
