Electric Field at Dielectric Interfaces

[iamkbatra]

Greetings Elmer Community,

I'm currently working on a system that involves two bodies with different dielectric constants, and I'm interested in calculating and extracting the electric field at their interfaces -- due to the discontinuous eletric field there are two different values for each node at the interface. I would greatly appreciate any guidance or insights on how to accomplish this within the Elmer software framework.

Thank you in advance for your assistance.

Best Regards, K Batra

You could have a discontinuous boundary where the bodies do not share nodes. Then you can use mortar conditions to enforce sharing data across the boundaries, and then each boundary for each body can have its own condition. Elmer even automates some of this with discontinuous boundary = true.

Thank you @kevinarden, I will give it a try your suggestion in my input file
