Dear all,

It's weird that I followed every step in the manual but got a wrong result for thin layer diffusion model. I'm a COMSOL beginner user; would anyone who knows the reason tell me how to resolve it? I've attached the model result and what I did. Thanks a lot in advance!

I've solved it by comparing the model and my work step by step. The only thing I missed last time is that I haven't chosen the identity pair in the continuity session. Thanks!

Hello

good you found out, normally if you go through the model step by step it works (I have not so far found serious errors therein) but I have too though I got everything right, but the results were wrong and then it took me some time to find the "missing item". On the other hand, by plotting out other variables to try to verify what went wrong, I learn a lot on how to plot, how to best validate and verify my models

Good luck
