I am a fresher in Comsol, so I am starting with a simple model (as shown in the image below). I want to do some model with surface reaction in the diffusion model. I have couple of questions>
1. how can i define the sensor area in comsol? I can do the different with rectangle and circle, but I can not do this with line and rectangle.
2. which model i need to choose, does the Nernst-Planck equation requires at least two different solutions?

Hi
one way is to define a variable as the integeation of operand "1" over the boundary, this applies also to volumes for domains etc.

Good luck
