Default Multiple DEFINE_PR_RATE UDFs in parallel

JeroenH is on a distinguished road
I am using a DPM and species model with a DEFINE_PR_RATE UDF for calculating the reaction rate of my particles.

Currently, it is only a one step reaction with thus a single reaction rate. Now I want to expand this to a three-step reaction where there are three different reaction rates.

I can however only couple a single DEFINE_PR_RATE UDF from what I believe. Is there any way I can either couple more of these UDFs or make the current UDF return three reaction rates?

I have also tried modelling my reaction with a different DEFINE_DPM_HEAT_MASS UDF, though I found this results in a substantial numerical error (I think this has to do with stabilization).


Any help would be appreciated!
