Hi there, I think your variable is only defined on the boundary and is not a global variable. In any case if you want to plot your variable try going to Post processing->domain plot parameters select the "surface" tab then select the boundary on which you defined the variable C then type C in the expressions field then hit apply.
Hope that helps

I am also trying to model a simple parallel plate capacitor but I do not really know where to start. I used the AC/DC electrostatics 3D model. Where can I find more information about modeling the electric field between the plates as well as measuring the capacitance?

To Ryan: Thank you very much. I tried the other way and I successfully get the result.
To Christo: I recommend you to read the examples in model Library of MEMS Module and try to do them yourself. It's really helpful.

Ryan: I think your variable is only defined on the boundary and is not a global variable.
I get the same error message. I defined my variables in global expressions yet I face this problem. I can plot using surface/point in post processing mode, but this doesn't let me plot multiple global expressions in a single plot. If plotting from global expressions work fine, making multiple plots in a single graph would be really easy.
Any suggestions?
Regards,
Rajesh.

Hi Rajesh, that is very odd, you should be able to plot your variables in "Global variables plot.." I am able to do so in my models, perhaps you could email me your model and I could have a quick look at it. Did you update your model after defining the variables??
