Hi. All fluent users !!

I'm studying boiling phenomena.
And I use VOF model in fluent.

I wrote UDF about it. but it didnt work.

My UDF has C_UDMI macro. So I assign memoris using User-Defined Memory.

I don't know how this error happened.

I attach my UDF files and equation.

Tell us more about the error it gives you, are you preallocating the UDM?

It could be either the way you handling the UDF is wrong or your algorithm is not correct (I'm not familiar with boiling mechanism). I think you need to guarantee you handling the UDM correctly then moving to specific algorithm. I personally spend around 25% time just to make sure I am using UDF correctly.

I'm a beginner having less than 3 month of experiences. I first used UDF. So I didn't understand this error.

I think your advise is right. so I'm fixging UDF.

I'm so sorry but Could you send the file by e-mail.

Please.

My e-mail is orchiders@nate.com
