Hi again, thanks a lot for your fast reply.
I am going to be a little more specific on my problem cause I don't think I am being clear.
I am studying the difussion process along a tissue wall (after damage by a medical device is done) where different cells migrate, proliferate and die and substances are degraded or produced. The fluid part is not implemented yet so there is no convection, just diffusion.
There are two types of cells that diffuse and some substances that degrade or are produced and regulate the proliferation or apoptosis of these two cells species.
The geometry is composed by two diferent layers that are subdivided in other domains.
The endothelium layer is divided in two halfs. One half has no cells and the other half has cells that diffuse and also move to the second "emplty" half (which at t=0 has no cells).
The media layer is also divided in two parts. One part has an initial concentration of other cell species that diffuse around, and also to the emplty part of the media layer and to the endothelium.
I define the difussion of each cell species with two different "transport of diluted species modules" where I define the initial concentration, boundary conditions, diffusion coefficient and reactions.
I also have a differential equations module where I define the substances behaviors and the initial concentrations.
When I run the model the two types of cells that have diffusion only diffuse inside their own domain and the concentrations of the cells and substances varies but the cells do not appear on the neighbour domains where I want them so maybe I am not setting right the boundary conditions for the diffusive species??
I hope I am a bit clearer now.
Thank you very much for your time
