Advection-Diffusion-Reaction Equation coupled with Cahn-Hilliard

[marie BELLA]

Hello,

I hope this mail finds you well.

I would like to represent the 1D transport and the speciation (transformation of mercury species into methylmercury) of mercury in surface water. I think of using the advection-diffusion equation as in the fipy examples to describe the pollutant transport and to use the Cahn-Hilliard 2D example but in 1D to describe the transformation of mercury species into methylmercury.

Please my questions are:

1- Is my reasoning correct?

2- How do I do this, since I'm new to Fipy, Pytoh, Programmation,...

Thank you in advance.

Yours sincerely,

Marie.

Advection-diffusion combined with Cahn-Hilliard could work, as could advection-diffusion-reaction equations. What is used in the literature for your field?

If you have identified a mathematical model, we can help you implement it in FiPy. Your question as posed is too open ended for us to help.

Also, the mailing list is deprecated. Please use GitHub Discussions in the future: https://www.ctcms.nist.gov/fipy/documentation/CONTACT.html#github-discussions
