I am trying to simulate a wave of water in 2Drectangular tank using Vof model

I want to see the evolution of the  free surface of water in absence and in the existence of surface tension 

Do I need to write my own UDF Code to change the value of surface Tension

In the picture attached here is the evolution in Matlab I want to do the same thing in Ansys Fluent

Thanks

If surface tension is temperature dependent UDF is not a must.

I want to do this equation of surface tension

Hello,

Yes, you will need to write a UDF for this.

Best,

Thank you Kremella 

Could you give me an example how to write it I have little experience in coding C
