Hello everyone,

I am running DPM iterations on Fluent.
I have a transient solver with a UDF function for velocity.
I stop the iterations at several time steps and inject particles and see the effect of the change in velocity on DPM concentrations.
However, the iterations are very slow (1 DPM iteration takes like 15 minutes or more)
The DPM iterations are steady and it's a one way coupling

Does anyone know why this is happening and how can i solve this? It's urgent


Thank you
