Default UDF for VOF
Pei-Ying Hsieh
Posts: n/a

I am working on a multi-phase problem. A tube is filled with water at t=0, then, an air bubble flows into the domain at the tube inlet. Due to surface tension, there is a curvature at the air/liquid interface. How to use UDF to specify the air volume fraction at each grid point at the inlet (as a function of time)? Thanks!

rsingh7 is on a distinguished road

I need to calculate force at the interface in VOF simulation. Using CSF model, one need to compute the curvature of the interface. Can any one help me to write fluent UDF for this.

I will really appreciate for this.
