adsl17754 is on a distinguished road
Hi all,

I am doing multiphase flow simulation, and I'd like to do a validation case to evaluate the performance of VOF method in FLUENT.
In order to simulate the validation case, the velocity field needs to be defined as:

How should I define the time-depedent velocity field in FLUENT, is UDF a practical solution ?

Any suggestion is welcome, thanks in advance
