Reflecting and absorbing boundaries
Hi, I am new to Comsol. I would like to model some instantly released molecules inside a reservoir. The diffusion coff of these molecules is 6e-7 cm2/s. I have some questions about it. 1. How can i...

Transport of diluted species is not suitable for tracking individual molecules, it works on the scale where one can speak of concentrations. I do not know if COMSOL is suitable for simulations of...

Actually I want to track the flux of the molecules on the absorbing boundary and not individual molecules. Also I would like to define some boundaries that reflect the flux back into the reservoir. Thanks

By reflecting you mean that the boundary is closed (i.e. no flux)? What kind of boundary condition do you have in mind for an 'absorbing' boundary? You mean that every molecule of your diffusing...
View ArticleRe: Reflecting and absorbing boundaries
Yes. By reflecting I mean that boundary is closed but the molecules are not going to be accumulating in the closed boundaries and instead they are going to be reflected back. And again Yes. By...

Yes, then indeed you can put the boundary condition as I said above. The flux through a boundary is called chds.bndFlux_c (if chds is your transport of diluted species physics and c is your diffusing...

Thank you so much, First of all do you mean line integral in Derived Values? If so I did as you advised. However as I said I want the Flux vs Time (ie. the flux at time=.2, the flux at t=.3,...) when I...

If you have specified the times at which you want the flux also as times in the time dependent study, and then if you choose for the line integral (you have a 2D model I guess?) to evaluate it at all...
