HELLO!

I'm trying to model a scenario where particle movement happens via diffusion and also there are particle interactions with the channel wall.

So, I should use both DPM and Species transport models, shouldn't I?
My questions are,
1. Can I use both models in one simulation?
if yes, I can put the UDF for interactions via DPM model, and the species transport model will take care of diffusion flux.

2. if no, should I use DPM model and extend the UDF with DEFINE_DPM_HEAT_MASS macro to get diffusion flux

3. Or, can I include a body force on diffusion particles via the species model? Can I use DPM_BODY_FORCE macro in the species model

Please help!
Thank you!

Yes, you can use species transport along with DPM model
