Looped Electro Thermal Simulation in the Frequency Domain

Please login with a confirmed email address before reporting spam

Dear all,


I'm currently trying to perform an electro-thermal simulation, where I calculate the average joule heating in the frequency domain and use this result in a time dependent study calculating the heat distribution.
To improve my results, I introduced a for loop inside my solution and iterate between these two steps. Such that the execution flow looks like:

Step 1: Freq domain (ec) (only initializes a solution)

begin for
Step 2: Freq domain (ec)
Step 3: Time dependent (ht)
end for

Now I want to update the simulation time for step 3 depending on the parameter of the current iteration. Furthermore, I need to decrease the applied current (still sinusoidal) depending on the current simulation time. Is there a way to access these variables? I'd rather try to avoid matlab for license reasons. But if needed, I can use it.

Thanks in advance.
Philipp

Dear Philipp

COMSOL has a special built-in functionality for exactly that type of problem. It is called study type "Frequency-Transient". There is little need for manual work because the necessary updating steps are already built-in.

You find a tutorial that uses it here:

Additional information can be found here:
