  Greetings
  
  Respected experts I hope you are fine. I am working on simulation of bubble growth. I am doing volumetric smoothing initially and add mass due to evaporation in certain cells. But after sometime this smoothing disappears. There is a mention that we can do such smoothing later on as well. But probably it would be a manual work for which we have to stop simulation. Can we adopt this method without stopping the simulation and is there any way that can help me.
  
  Thank You

  There is a smoothing option in the VOF patching tool in Fluent. Not sure what you mean by smoothing later on: won't that change the solution?

  Yes it would change the solution but in my case it cannot impact to most the parameters that I am studying. Can we change it later on without stopping our simulation???

  No. You need to stop the simulation or adjust the whole code to add additional smoothing.

  Respected Sir sorry for replying late. Will adjusting the code do you think it would be difficult task. I do know some basics of UDF. Do you have any kind of tutorial or any kind of data that can help me with it. Would be thankful for you coordination.
  
  Thank You

  The only UDF guide we can share is in the Documentation for Fluent: you can access this through "Help" in Fluent.
