Hello,
I am attempting to model the evaporation of dilute species in an additive manufacturing process. For each added layer of material we have applied a boundary condition at the bottom, concentration C_0, and a boundary condition at the top, surface concentration C_s which is depleted of the dilute species.
We have a problem when adding additional layers due to these boundary conditions. For the first layer we have a concentration gradient from C_0 at the bottom to C_s at the top. However, when adding the next layer the top boundary of layer 1 (C_s) becomes the bottom boundary of layer 2 (C_0). The difference between these two concentration values is quite large.
What is the best way to approach this abrupt change in concentration at the interface between these two layers?
Thank you for any help,
Thom
