I would like to simulate sublimation model in Fluent.
I want to define the mass of solid as an initial value. Where can I define it?
I can't find the way to define it.

Thank you in advance.

There is no in-built mass transfer model for sublimation. So, you have to define it yourself. Mass is never provided as initial value for any field. It is always the size, provided as mesh, and the material density. Then those are used by Fluent to define the mass.
