CFD_DEM Coupling- Particle drying

Eddy_94 · December 28, 2023, 02:21

Hello Everyone,

I am trying to simulate the particle drying using Fluent and Rocky DEM two way coupling. In DEM there is one module ' CFD Particle Drying Model '. In Fluent setup I have used Eulerian Multiphase model (2 phases air and water vapor [solid phase will be solved by RockyDEM]) with species transport (mixture templete air +vapor). In DEM I have used CFD particle drying model, to which the required moisture conent has been given. The coupling option is chosen as '2 way unresolved'.

But when solving in DEM it is giving me this error:

I am unable to understand the source of this error. How can i fix this error?

Thank you !!!
