Modeling Drying and moisture tracknig

Hi - - Do we need to write udf to modify the code in order to model water evaporation and moisture tracking in a fluidized bed or the software can do it without any modification? Actually I want to simulate the drying process of a mineral with TFM model in a fluidized bed.

Yes, you need to provide the kinetics in the usr_rates.f.

The kinetics in the usr_rates.f determines the rate of evaporation. Do we need to define moisture content of each phase as a scalar to track it in each phase(the convection and diffusion of the species in each phase)?If yes, Is there any tutorials which implements the scalar equations?
