hello,
For my post graduate project, I have to model transport of a drug through the eye using molecular diffusion(Fick's law).

There are three different layers over the eye. All of them are solid and non-porous. The implant will release the drug into the eye over a period of 8 weeks.

The drug will then diffuse through the different layers of the eye into the center which is porous.

I however am unable to find the correct module which contains the equations for this purpose. Any help would be appreciated.

The implant is situated just above the optic nerve.

I have attached the image of the eye model I am using to provide further clarity.
