surface reaction dynamic

Teo Fumagalli

Hello,

I have to simulate the deposition of compound A in acqueous solution on surface along with time (I mean that I want to monitor how the deposition rate change with time). The deposition has to take care of the fact that an occupied active site can't react. I've already simulated the steady state case successfully. The only problem I encountered is that the coverage of active sites can't be displayed; well actually it can be displayed but the plot doesn't show any point.

Can anyone explain why is that? And any hints about how to implement the dynamic simulation (if possible without using UDF).

Thanks for your consideration
