Help configuring Sequential Frequency Transient study for heat simulation of antenna.

Please login with a confirmed email address before reporting spam

I am modelling a microantenna structure on 2 silver wires connected with a lumped port. Using the frequency domain, I have been able to vary for different frequencies, and study the resulting microwave field.

I am currently trying to perform heat simulations. I would like to study how the temperature of the antenna varies in time for different frequencies. Unlike the usual RF heating studies, the lumped port input is manually configured. I thought the Sequential Frequency Transient study would help with it. However, the simulations appear to be independent of each other. After the first attempt, i obtain the error,

  • Feature: Stationary Solver 1 (sol15/s1) Failed to find a solution. Matrix has zero on diagonal. Returned solution is not converged. Not all parameter steps returned.

The second attempt shows me that the simulations are not influencing each other. The temperature study is independant of the frequency.

I have tried inputing the heat source as the power losses emw.Qh, to no avail. I'd appreciate any help.

The only way i was able to account for this was assign the frequency changes to the parametric sweep

Thank you.
