Hello everyone,

I start the user Elmer and I need a help.

How correctly to set a similar configuration for calculating the electric field inside the tube (black-dielectric):

The black side - dielectric, orange side - anode&cathode.

I need to calculation electric field inside a tube but with some specificity. So, from 0 to Alpha_1 we calculation with potential Phi1 and Phi2 on r1 distance , but from Alpha_1 to Alpha_2 we calculation with potential Phi1 and Phi3 on r2 distance. How do I set this range in Elmer ? I created geometry in GMesh, namely one cylinder placed in another.

I'll be very grateful for the help!

Regards,

Alex.
