I have two DPM injections of different particle types and at different locations, one injection is intended to represent CO2 bubbles that will dissolve in the aqueous phase which I had previously gotten working. The second injection is solid particles that are intended to grow in size based on the concentration of a corresponding species in the continuous phase. In order to distinguish between the two seperate injections I am trying to use an if-else statement shown below, with the associated &#8220;include&#8221; statements. When I try to compile using Fluent&#8217;s built in compiler I get this error.<\/p>\n<p>lld-link: error: undefined symbol: TP_EVAP_SECIES_INDEX<\/p>\n<p>This would seem to indicate that that TP_EVAP_SPECIES_INDEX is not a recognized macro despite it being listed in the Fluent customization guide and me having the dpm_types being loaded in the UDF.
