Hello everyone,
i want to attach the electrodes to the boundary of my model , but when i am try to mesh or add the sub domains, it shows me error
"Could not resolve subdomain relations"
could you please tell why it is coming?

Hi

that has to do with the way COMSOL manage to understand your model assembly, try to group it or convert the different items into a "solid", that might help, or it's just that your points and lines "almost" match, but not fully numerically (there were different resolution relative and absolute values too, somewhere back in 3.5 ;)

Good luck

Hello,

Thanks for the explanation, can we say that it can be solve by changing COMSOL version?
and also i am getting this error when i am adding "Union" the two objects
"Internal error in geometry decomposition."
why this happened

Hi
there can be very many reasons, even simle geometry can be rather complex from the point of view of topology decomposition and recombination.

newer versions tend to be better, but it might not be enough for your model, impossible for us to tell like that
