Surface etching depending on concentration
 

Hi,

I've been using fluent to look at concentration gradients within a microfluidic device.

Does anyone know if it is possible to model etching (and hence find the subsequent change in shape) of a solid using the species transport, and if possible thermal, data?

i.e
1. Solve for the species in the initial channel
2. Alter the mesh to remove parts of the solid (more removed in high concentration areas)
3. Iterate, etc.

Cheers,
Ben
