Hello,
I am currently working on a project to simulate the electric field behaviour at different temperatures. The application is shown in the attached image. I already simulated it in DC with the temperature dependence as 2D axissymmetric model. Therefore I used the "electric currents" and "heat transfer in solids" physic coupled with "electromagnetic heating". As study step I used "stationary". Now I want to do the same for AC. I tried using the "frequency-stationary", but I always get an error while computing.(First few rows of the error code are at the end of the post) I couldn't figure out why the solver gets that error. Hence I looked for a different way of solving it and changed "electric currents" to "magnetic and electric fields" because I saw that in an example. However, in this new setup I can't apply the voltage on the electrode or the ground.
I am pretty sure the simulation should work with my first attempt, does anyone know what I did wrong or what I can/should change?
Thank you!
