Hey Rob Thank you for your time. I am sorry for the bumps, I am pressed for time to learn this.
So when we assign a material (say As created under fluid material) to a 'solid species' when running a surface reaction, and the material is modeled as given out as an etching ( say As is a product of the said surface reaction) then the resultant Arsenic etching (solid species) is simulated as a DPM?
When the "Species Transport" model with wall reaction is used what is the difference in behavior between Adsorption/Desorption (for site species) and Deposition/Etching (when using solid species)?
