Question about Nernst-Planck Model

Hello,

I'm a new user for Comsol 4.2. When I applying the Nernst-Planck model form my work, I added 5 species, c1,c2,c3,c4,c5 which zc1=+1, zc2=-1, zc3=-3, zc4=+1, zc5=+1 and set the 'from electroneutrality' option to zc3.

My question is: which species' concentration is showing by the resulting chnp plot? Is there any way I can show the whole concentration (c1+c2+c3+c4+c5) in one plot?

Thanks
