Hi,
I am running Eulerain-Eulerian multi-phase simulation with air (primary) and water (secondary) phase. I have studied UDF manual. We can write UDF only for granualar diameter while using Eulerian model. Is this the case? Or we can write for droplet/bubble as well?
I have written UDF for droplet diameter(water) which gives segmentation error when I use Eulerain Model but when I use Mixture Model, UDF works fine. What are the possible errors?

dear friend,

im working on the similar topic
can you lease share your UDF. i want to know how you acess to the different phase, I need the volume fraction of the different phase at each cell
