Coding Boundary Conditions - Reaction/Diffusion system of PDE's

Hi guys,

I am studying reaction+diffusion problem in chemical engineering and I am struggling very much with coding boundary conditions in pdepe. I really dont get it from https://www.mathworks.com/help/matlab/math/solve-system-of-pdes.html how should I code boundary conditions...

The system of interest is defined with a following equation:

whereas my boundary conditions : are for and for . I am considering system in the slab geometry, therefore . is the source term. ε is the constant.

I have written a short note that describes how to define boundary conditions in pdepe.

You can find that here. Hope you find it helpful.

Hi sko,

I am also facing the same issue regarding boundary conditions, were you be able to solve this issue?

Thanks

Hello,

Yes. Follow carefully the procedure from matlab Pdepe
