And it's used here https://ansyshelp.ansys.com/account/Secured?returnurl=/Views/Secured/corp/v212/en/flu_udf/flu_udf_sec_define_source.html%23flu_udf_udf_degas We're only able to guide using what's in the documentation where UDFs are concerned. Have a look at the multiphase specific macros and see how they're used as all then have examples.
