One phase is solid and the other phase is a gas. The mass source added is same as the solid phase. Can someone please tell which macro to use, DEFINE_SOURCE or DEFINE_DPM_SOURCE? I have read in a paper that it is an injection proper using DPM. But how to add a mass source in the continuity equation for a two phase problem?<\/p>\n<p>I have tried DEFINE_DPM_SOURCE when using interaction with continuous phase but if I use DEFINE_SOURCE, I don&#8217;t understand where to add the UDF?<br \/>Any help is much appreciated.
