Level set function in Fluent
 

Hi, everyone

I encounter a problem when simulating a multi-phase flow. I want to use the Coupled Level Set and Volume of Fluid (CLSVOF) method. In the forum, I find the level set function in UDF is C_LSF(c,t). But it have a error of LNK 2019, which means the function is not existent. Can anyone give me the level set function in UDF. Thanks a lot.

Best wishes for everyone.
